Although I first heard of BitCoin around 2010, I did not believe the stated words. And I missed a lot, I could use that money
Even though you have a lot of money, you can never buy into the past. Around 2010 you just heard about Bitcoin but at that time you were not at all interested in getting bitcoin because you didn't know how the nature of bitcoin.
Is (are) there any relatively new altcoin that could do some interesting increasing. That has good potential. It is difficult to notice every coin as there are now more 9000 of them.
As you have already said, there are currently over 9,000 Altcoins on the market. Some of us here can only provide suggestion for you, but if you don't do your research and have the knowledge of how to invest safely, everything you do will be in vain.
