I gather that Coinbase has had to release trading details for UK residents who have withdrawn over £5,000 in the last year. This seems to be in line with the demands of revenue departments in other countries. One result of this is that P2P transactions are likely to increase in the future, and details of these do not appear in the price movement stats.
How do you think this will affect statistical analysis of price movements, and should we be worried about this? I can see some large players recording losses on the exchanges to drive down the price, and then buying at a lower price in private transactions.
Larger players aren't going to try to skirt tax law with that. There's no reputable company, with that amount of crypto, that will just ignore the regulatory concerns of reporting this sort of purchase.
Just because CoinBase reports your stuff to the IRS doesn't mean that other companies just get to ignore it because it's a private transaction. Do ya really think the IRS is going to be all happy with the fact that you wired 50M to someone out of the country randomly? That'll probably be the reason for a red flag and a explanation on your part.
Not the way this is going to work.
