Don't put all eggs in one basket, if i were you i would be bitcoins, ethereum a part of them holding and a part of them trading if you have knowledge, mining is only profitable if you have free electricity but we will not know what will happen at the halving time.
Yea, i think everything is profitable but you have to handle it proper way. Maximum of us start mining without proper knowledge or if we go for investment that also without proper research. So please invest your money when you gain huge knowledge about crypto market that may be mining or trading or IEO investing..etc.
thanks.
