I never want to invest on any of altcoins by selling my bitcoins because I knows that bitcoin has more potential than any other coins so it will give more benefits in future if we hold until,if you invest on altcoins you can invest the amount from profits of your bitcoin.
Well i think about that also we cannot actually sell our bitcoins in order to buy altcoins, as we all know bitcoin has more potential than other coins. If we hold more in bitcoin right now maybe in the near future it gives more benefits than other altcoins.
