May as well just sit on the sidelines for a while I wouldn't have sold until the Bitcoin Gold Split personally but since its already done, you could reposition yourself into altcoins which took a big hit or keep the earnings and do a wait and see it is good money after all.
This is just one smart move! Buy, hold on for the split, buy the alts with potentials as most of them will definitely end up being pumped and make a huge shitload of profit from them with whatever you get from BCG while holding your BTC.
Is not that just a very cool and smart way to make some real good bucks rather than thinking of selling and hoping for the value to come back down. just a very wrong move at this point in time.
