So with the recent spike in BTC price (and other ALT coins) when is a good time to sell?
There is no better time than now op, if truly you are hodling BTC or ETH because their price has pump higher in this month of November that made many people to sell off their BTC and altcoins to earn profit which you can also make a good profit from those coins, if you can change your mind to sell. I have sold my BTC before the price hit $90k because I feel it will not going to pump above $85k before it will return back to bear season, but what I saw few days ago in the market make me to agree that BTC and ETH will pump more this year, if the green night continue to shine in the market.
Honestly when it comes to BTC, then there is no altcoin I would defend against it at all. If anyone wants to sell all their altcoins and buy BTC then I would say I support it, to be fair I would also support it if they decide to keep most of them too, depends on the coin or the token of course, like if they decide to keep ETH or BNB or SOL or LTC, all of those are fine to me and I would respect that decision, but if they want to sell those and get bitcoin then I would respect that too, either case seems like a good one.
The only way I would ever get involved would be if they have some shitcoin, and I feel like File Coin could be one, rest seem like they are just ordinary coins that we have all heard of and nothing bad, they are all decent enough and feels like they should be considered as good and decent. So whatever OP decides to do, I am here to support it, aside from just one coin, the decision to either keep them, or sell them for btc, both seems like good ideas.
