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.
The problem with these altcoins is that even if you buy them at zero value, you will never know if their value will truly appreciate in the future that’s why some invested on them and end up regretting, wishing they only stick to bitcoin regardless of its quite expensive price. I guess your friend was just lucky that time, because if he insist it doing again these days, surely he will only suffer from great losses.
