If ever I have to do that, I will choose Bitcoin. We all know that among all the cryptocurrencies, bitcoin is the most established coin 50% of my investment now is on BTC. And if all holders of other cryptos would need to dobthe same, for sure BTC price will soar high.
For me the bitcoin is the right one. Because the value of bitcoin now is absolutely amazing, and it will continue increasing its value for the next few years (the bitcoin experts predicted that), so that if you invest now in bitcoin their is a huge possibilty that you will earn a huge profit and your future is guaranteed secured in bitcoin.
