HODL, I think that's the best for now because I think almost all altcoin, is currently experiencing a price down. So just wait until the moment when all altcoin rise again
I agree with you, it's best to still hold our altcoins and not to sell it at a lower price most especially if we invest it before at a higher price. We should wait and hodls more until our coins rise back. Altcoins will recovers again especially to those top altcoins that has strong foundations and useful technology.
