If you want big profits, you should accept big risk. Both choices can be and unfortunately, it is impossible to know which one will happen. I think it is better to try as you can risk, otherwise you may lose all your money. ''Greed is good, but when the time comes.''
That's true. For the longest time, this market has really solidified the strategy of high-risk-high-reward. If you would do the necessary leap of faith in order to make it big, then this market could surely do a lot and bless you beyond your wildest dreams. It's difficult, especially these days, in its current state, but it is still possible nonetheless. As for the question, I would say that betting majority of your coins into Bitcoin could be a good strategy; however, diversifying can also be a good strategy still, especially if what you are eyeing on are those seasoned coins that have showed many good trends in the past few weeks and months just like Ethereum. That way, you have several leads to follow and not just wait for Bitcoin all the time.
