I saw something on a friend of mine iPhone I was amazed, this guy has 3 pieces of bitcoin but he didn't look it when you look at him with mere eyes, I ask him how he has come this far, he told long ego he was seriously investing on all kinds of coins with little amount of bitcoin but then most of those coins help him to realized enough amount to buy.
@Op your friend invested in the right place at the right time. Especially at first more than half of assets were invested in Bitcoin and some assets in AltCoin section.
But benefiting from that is currently staying within Bitcoin. But your friend also knows that Bitcoin is the best among cryptocurrencies so Bitcoin will be the king of cryptocurrencies now and in the future.
