Bitcoin will be the first thing we should have and then altcoin because bitcoin can give us a big profit. Some people are trying to buy altcoin first then buy bitcoin because they think that with so many altcoins at the market, they can get huge profits from various coins and that profit can be in bitcoin forms. So that means it will be the same thing because, in the end, they will have bitcoin and be ready to sell at a high price.

But I suggest you buy bitcoin and altcoin to give you a chance to make more profit. It will depend on each people because I am sure that we have a different plan to make a profit.
