Central exchanges, on the other hand, require you to physically send your crypto asset to a different wallet address and then trust them to credit your exchange wallet with the said crypto. In reality, the numbers you see on an exchange are just numbers and your assets there are only imaginary.
This part made me remember the movie, Trust no one.... It made me realize sending money to exchanges is a risky move, and you might or might not get your money back. It was at this point, I realized why we keep getting people preaching that our coins are safer in our wallets and not exchanges.
