It is very difficult to manage strategies about your crypto trading because the price is not stable and in this situation It is difficult to handle this bearish situation in good way. I think that traders should hold their coins for some time to pass this reddish situation of the market and when they see greenery in the market they can start trading again. Till that time they should hold their coins.
Whenever you the price of Bitcoin increases then you should start thinking to sell your coins if you are in profit then otherwise it will lead you in bad situations if you sell directly without monitoring the market value. The current value is 6488 US dollar so remind your cost price of what amount you bought coins and then subtract that from the current price so if you are in profit then sell it.
