Yes you can learn from this froum.You can learn about bitcoin in Bitcoin Discussion ,project development. You can learn about altcoins from Alternate cryptocurrencies thread.You can learn about trading from trading Discussion thread.But you need proper knowledge before start trading. But I think mining is not a good choice.Need huge investment to start trading.Altcoins mining is profitable
