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.
Yes. very aggrieved when investing bitcoin. because bitcoin has a huge advantage. has a very high market price. I am sure by the end of 2018 there will be a rise in bitcoin prices that will rise and normal again
But why should you sell altcoins to do it? Invest in Bitcoin, using the money you earn on your main work. Many alts will give you more profit that BTC can do.
If you have money then it is good to invest your money in bitcoin then no need to sell anything but I am disagree with the last part of your discussion as you told us that many investment are better than bitcoin in the world but I think nothing can be better than bitcoin, it is high in profit, it is safer to hold and can earn highest profit for your future, so I will sell anything for bitcoin investment happily as I know how worthy it is.
