I choose to focus on altcoin because there areb so many profitable altcoin was born each year. It can help us to earn a lot, as long as we have enough knowledge to deal with it.
Well, everyone will basically have their own choice, but you have to understand that most altcoins are shitty anyway, so you really want to know the altcoin you want to be playing around with in your wallet. Things like this is what makes me assume if people actually get to understand the space they are investing in at all, or they are just simply looking for a way to get rich and get out whenever they can and then forgetting what they should be placing their focus on which is the future.
Earning is one thing, then knowing what you are into is another different ball game entirely and how will you be able to make decisions, if you really do not know what you are getting into?
