When there is panic in the market, which there is, you will always have people who sell their BTC and altcoins even if they have a significant loss.
All the holders will have profit in the end, but you need to have patience!
In order to have great success patience is our tool when market is not good. Some sold theirs due to panic sell so we cannot force them. Instead, believing it will rise and holding we can have profit at a latter end due to price will rise.
People who sold the coin are really felt very bad when the market starts recovering, people who are still believing the Bitcoin will always hold until the price of Bitcoin starts recovering. A higher percentage of the people will mostly panic about the Bitcoin price when it starts decreasing.
