That isn't to say they didn't profit by converting or selling over what they paid for it, but it has increased so much day to day since march...
Unrealized gains are not the same thing as profit. Your "gains" are worth precisely zero until you take profits (sell). So those that have sold, or those that sell constantly, are the only ones who have actually made money. Everything else is unrealized gains or potential profit.
The thing that people on this forum dont seem to understand is that missed potential profit is worth exactly zero as well. Yes, I might have made more potential profit buying and holding, but by selling I have locked in profits and mitigated any risk by exposure to a market that could tank at any point.
Those that refuse to lock in profit are the same ones that will be left holding the bag if and when the market crashes.
