I have withdrawn ETH from Cryptopia 24h ago and nothing happens. It shows in Withdraw History with status complete, but I can not see anything on the target address nor on the TX ID with etherscan. What happend? Anyone has the same problem?

I was active in mining scrypt coins in 2013/14 with cgminer on linux, but did only do trading in the meantime. I am totally lost now with all the different algos and new software which is available.

I want to come back with a small GPU rig, mainly for solo mining at the very beginning of a new coin for one or two days. I am looking for a mining software which supports different algos working on linux with AMD GPU.

Any recommendations?
