Crypto quiz

✓ Right: many copies are checked against each other, which makes old records very hard to change.

✗ A blockchain is a record of payments, not an account at a company.

✗ No one sets the price on a blockchain; buyers and sellers decide it on the market.

✗ Coins are entries in a shared record kept by thousands of computers, not files on one machine.

✗ Being a token says nothing about safety, and many tokens are created only to be sold to beginners.

✓ Right: this is why tokens are cheap and fast to create, and why there are thousands of them.

✗ Both are only entries on a blockchain; neither exists as a physical object.

✗ Anyone with basic skills can create a token in an afternoon.

✓ Right: with no cash flowing from the coin, the price is only what someone will pay for it.

✗ A small supply alone creates no price; something rare that nobody wants is still worth nothing.

✗ A team can set a starting price, but after that the market decides.

✗ The blockchain records payments, not a price; the price changes with every trade.

✗ The screen shows only the last trade; the buyers waiting now pay less.

✗ That would need all 5,000 tokens to sell at $1.90, but only 1,000 buyers want that price.

✓ Right: $1,900 + $2,250 + $2,000 = $6,150, which is $3,850 less than the screen showed.

✗ That would be all 5,000 tokens at $0.80, but the first 2,500 sell at higher prices.

✗ After an 80% fall, $100 is $20, and 80% more only brings it to $36.

✗ $20 plus 160% is $52, still about half of where you started.

✗ $20 plus 800% is $180, far more than you need.

✓ Right: $20 must grow by $80 to reach $100, and $80 is four times $20.

✗ That is roughly the size of the loss, not what is left.

✓ Right: $1,000 × 16,000 ÷ 68,000 is about $235, a fall of about 76.5%.

✗ That would be a fall of about 48%, but the price fell by much more than half.

✗ A fall of about 76.5% leaves about a quarter of the money, not nothing.

✗ The account is yours, but the keys that move the coins are held by the exchange.

✓ Right: your balance is the exchange's promise, and it can freeze, lose or misuse the coins.

✗ The blockchain accepts any payment made with the right key, whoever makes it.

✗ The bank only sent the money and has no control over the coins after that.

✗ One wrong character or the wrong network, and everything is lost for good.

✓ Right: the test costs one extra fee, and it protects the whole amount.

✗ Never give anyone your seed phrase; anyone who has it can empty your wallet.

✗ Only copy the address from your own wallet, and check it carefully.

✗ No real verification needs your seed phrase; typing it in hands over your coins.

✗ Part of the phrase still helps a thief, and no honest site needs any of it.

✗ Real support never asks for your seed phrase, by any channel.

✓ Right: a page that asks for your seed phrase is a theft attempt.

✓ Right: 1.02 to the power of 365 is about 1,377, which no business could pay, so the promise is the scam.

✗ That is $20 a day for 365 days without reinvesting; with the payments reinvested, the number grows far bigger.

✗ That is roughly what 1% per day would give after compounding for a year.

✗ That is 2% for one day, not for a whole year.

✓ Right: the organisers bought earlier and sell when the crowd pushes the price up.

✗ People rarely tell a crowd to buy unless they gain when the crowd buys.

✗ Arbitrage means price differences between platforms, not a crowd buying at once.

✗ A stablecoin aims for a steady price, which is the opposite of a coin about to explode.

✗ Real taxes are not paid by sending extra money to the platform to unlock a withdrawal.

✓ Right: real businesses take fees from the amount withdrawn and do not ask you to send more first.

✗ The profits on the screen are usually just numbers, and paying only adds to the loss.

✗ Verification asks for documents, never for a payment to release your money.

✗ This is exactly how romance and investment scams begin, often after weeks of friendly chat.

✗ Small first deposits often show a fake profit, to make you send more later.

✓ Right: someone you have never met in person bringing up investing is a strong red flag.

✗ A professional-looking website is cheap to build, and fake platforms often look very polished.

✗ That is where the full $1,000 is gone; liquidation comes earlier, when only $50 is left.

✓ Right: the position holds 0.2 BTC, a $950 loss needs a $4,750 fall, and $50,000 − $4,750 = $45,250.

✗ That is a 20% fall, which would wipe out the margin at 5x, not 10x.

✗ That is a 1% fall, which wipes out the margin at 100x, not 10x.

✗ $15 is the cost of one day: three payments of $5.

✗ That would be funding charged on the $1,000 margin, but it is charged on the full $10,000 position.

✗ That is 10 days of funding, not 30.

✓ Right: 0.05% of $10,000 is $5, three times a day is $15, and 30 days is $450, which is 45% of the margin.
