Much have been invested in altcoins and many are still coming up, yet many have not rely done well or lived up to expectation. Should one continues investing in altcoins or concentrate only in Bitcoin?
Currently? I advise to invest on Bitcoin only. I mean majority of your portfolio should be in Bitcoin like 60%-80% and then the rest of altcoins with real usage and back up by fundamentals.
Bitcoin has taking the majority of the market now, almost 60% and counting. Alts already suffered and will continue to suffer unless Bitcoin goes on a bull run taking most of the top 10 alts with him.
