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.
Yeah although I would suggest now buying soon after fork, price may drop to low $5000s when people would be busy selling. Below $5000 looks tough right now.
i panicked and i bought backed at 5620$
In the last night the price of bitcoin already touched above $5620 and that means you are able to get our from there and waiting for another correction in the future, Are you tried it? or are you just try to keep your coin at the moment? This means you are in the lost because the total amount of your bitcoin will be less thatn 17 bitcoin.
I think that another bullish will be coming in the next week before the fork and big correction after the fork will possible.
