In my opinion, Holding bitcoin is the best idea for the long-time. As you can see, the crypto market is fluctuating a lot recently so you easily get influence from it. You would get panic  to lose you money or somethings like that. eventually, you would sell your portfolio at the lower price. Bitcoin is the best potential coin. I think you just keep it until getting high like in the end of last year again. So your mind would be free if you're holding for long time.
