Very confused these days, dont know what to mine.

normalv7 on nicehash, bittube, graft, alloy or loki ?

Any advise ? for all the the new coin is there any exchange where they can convert new coins like bittube or graft live to your btc address ?

Also, please refer any forums or discord channels which i can follow for what i should be mining with current conditions.

My rig:
2xvega56
3xvega64
1xvega FE

Thanks in advance.
