Intelligent decision. I still have enough in Bitcoin and I do not plan to sell it now, but from my perception one should only buy in those cryptocurrencies in which you have hope, I have used this time to buy some options like SmartCash or Cardano that I see good in the long term, due that with the market going down there is not much to do, but I also think that the BTC can still have a couple of good rises, so I leave a substantial part in it.
After all, it is a matter of seeing that it produces more profits, because certainly in this market virtually any cryptocurrency has so far produced profits for people, at least for those who are patient.
I own some Cardano myself I believe around 800. I don't remember if SmartCash is one I own or not. :)
I personally trust that both are undervalued and have a long way to go, they are good bets to diversify the portfolio.
