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.
Well if he said long ago then my first thought would be when 2017-2018 era where altcoins was really rising and shining back at that day because every ICO is really fresh and most of them were pretty much got listed into exchanges after the ICO was over so your friend probably used that opportunity to grab some low price altcoins especially during that Bitcoin's bull day it was really great for the traders.
But nowadays, most of the projects are just trash and some of the new altcoins are not worth it to invest even if you diversify your investment. That's just means you are throwing some free money into them, it's really different compared to what we had before.
