It seems to me not worth selling coins. There is a big chance that the price for these coins will grow faster than at the BTC.
if you look at the price level in 2017, then the crypto-currency market fell at least 10 times. Thus, we can assume that when the market is restored, prices not only return their previous indicators, but also show new highs.
Most of the alts value now was affected by this bearest market so value was likely down and selling it right now will give us loses against invested capital whether it comes from bounty rewards because the fact that we spend effort for it. But its your judgment as its your coin but remember and ask your self if you are selling for your profit or not.
