It depends on your goal. I mean why do you buy them? If you buy them to make a profit, then bitcoin is actually the best. It is true that its price depends on the market but it is doing well actually. If you have crypto because you want to use them in everyday life, then no problem. In that case, they are all good. I think the best thing is to do both. Buy, use for business and make a profit if possible. It is just a long-term investment. You have to wait if you want to make a good profit.
