First, what you have to understand is that every decision you make will have an impact, whether positive or negative, the most important thing is to respect the decision you make so that there is no deep regret. Basically bitcoin and altcoin are equally profitable, depending on your analysis and foresight in positioning yourself in the market, if you regret having bought altcoin and if hold bitcoin will get more profit, the question is whether you can survive to hold bitcoin when the price drops dramatically? it could be that you take it off before going up. So, let's be wiser, dividing investment in bitcoin and altcoin isn't bad either, instead it can be an alternative to avoid big losses.
