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 more bitcoin because that was his primary target. He normally buys those zero value coins when they appreciates it will be enough money, and that's how he convert and swag all to bitcoin and today, he has 3 piece. Is good to be diversified in your investment, somedays something good will come out of one you don't expect.
If this is indeed the case then your friend is a lucky one, he may have already made more than his investment. Your friend may have invested in various altcoins before investing in bitcoins and got huge profits from them and bought bitcoins with them. We have seen some altcoins which give good profit within short period of time if one such investment your friend got good profit from here and invested in Bitcoin. and he started investing from a small amount and gradually increased the number of bitcoins to hold the bitcoins for which he has three bitcoins today. You didn't mention here, when your friend bought the bitcoin because we know the price of bitcoin was very low at one time maybe he could have invested then. And your friend must be risk averse because Bitcoin will at some point be in a position that will make your friend a big guy. If he keeps the bitcoins in a good wallet from now on then it will be good for his money and will be safe.
