My questions are the following:
1. People who own hundreds and thousands of Bitcoins, where do they trade? It's risky to deposit such a high amount of coins on platforms like Binance and Coinbase because you aren't guaranteed that they won't block your account, even immediately after you deposit them. So where do they trade?
2. How do they convert their Bitcoins into fiat? I know that years ago there were some bank transfer deals on this forum, I remember that Bitmain wanted to sell 10 Bitcoin or something like that here and they probably had a deal with a forum member but today when the price is so high, where do these big holders sell their coins and get fiat in their bank account? On traditional exchanges?
When the amount to be released in an exchange is really large, it seems a bit scary. Of course, it's a centralized platform, as if they have the ability to really freeze your account or ours. So it's really safer with hardware wallets, or maybe with DEX platforms or non-custodial wallets, where only we have control over our wallet accounts.
Or it is also possible to release little by little, not a sudden large amount, because they will really question it; that's why the risk is still there. I haven't even experienced such things yet.
