Hold we need to hold when crypto is down spending crypto coin when it is down is a loss, because its value drop and you can only buy few things when its value are down , for me holding is the best option to avoid losses or is you cant hold swap it yo stable coin.like usdt, busd, etc..
Apart from having to hold back when prices fall, some people also take advantage of falling prices to buy back assets they like with the reserve money they have and I think that is also a good enough thing to do apart from having to hold on when the price is declining. And I also often take advantage of the decline to target Bitcoin at low prices, although not in large quantities because I only buy according to what I have, besides holding on to what I already have.
