We have different kind of currency on Hold and some of them are those we trusted more that is why the chance of selling altcoins are not in the first place but at least review our folio and look for the out performing currency and consider selling why Bitcoin halving is just soon to come.i have sold one of my coin last week and bought last night because the price fall below 10k usd again
But you do not have to sell all the altcoins that you have, because I think the altcoin season has not come, I know the decline in Altcoin yesterday was one of the price effect of bitcoin falling, but the potential to bounce back is still there
I also there is big potential in this space so when the real bull run will get started than everything will get exploded. That kind of correction is also necessary it make the trend more healthy and strong to keep pushing it towards the moon.
