I think it's Better to not buy now because we are in red market and i think we will keep going down unless there will be good news to pump the prices up
The perfect time to buy and hold was when you see that bitcoin price was falling like what happening right now. Becauae the more you buy and hold for it until it price pump again, surely a big profit will you get. It just a matter of patient because when you sell it during its price was low, it just like you waste your money.
