Some examples:
- NuCypher goes up quickly on binance (a few months ago) because a whale is buying there, lots of people try to withdraw on CB to sell on binance, withdrawals start off working but then get locked for 5 hours straight, reddit and other social media had people complaining, no explanation given by CB, just technical issues as always.
- Try to sell a few tokens a few weeks ago, it doesn't allow me to put big orders, instead they make me do it in multiple times, in which time the bots (some of which are theirs), front run me and instead of sell at a 5% lower price in one hit I lose 10% just waiting for the UI to allow me to make small order after small order.
- Always blocking withdrawals in the most suspicious moments imaginable, just happened to me 3 days ago trying to withdraw USDC, had to wait an hour until that "unexpected error occurred" disappeared.
- Human greed, why would they be different from the banks? I see most people don't withdraw their coins, I lend their coins for interest and profit from it, shareholders are happy, I sell my stocks and make money, if a bank run occurs I'll declare bankruptcy or ask the government for help because like a bank if my customers lose their money they might become unhappy and cause the government problems (Coinbase will eventually become a bank if crypto hype keeps growing).
