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.
Sometimes I think so but now they are not high price, but I will patiently wait for next I hope someday the price of the bitcoin I buy and hold will increase as they increased in their history was increased it so wonderful
