why all coins are going down..? can i sale it or hold.
Market downturn, Main crypto (Bitcoin) lay down, so another coins go to low. If you have a little bit amount, then I suggest you to sell it. But if you collected big amount of coins, then I tell you for HODL. Hold is gold, so keep patience and wait untill market up.
I do not think it's a good idea to sell with a handful of bitcoin, and everyone knows it's rumors or other reasons that cause panic, just to get you to sell your bitcoin and buy it at a low price , I suggest not to be fooled, hold and be patient.
