Its is indeed smart to not sell any coin. And that is quite good. the value now is not that high to sell it so that is good.
I think its better if you wait a little longer than you can sell it with profit and that is very goo.
Yes, patience pays, just hold your coins for next couple of months until the halving occurs, its not the best time to sell now, as the price is not the best one, but if you wait little longer, you can sell it for best price.
