Wow, I don't really know why you choose to invest in this coins that you mentioned when there are other coins out there that you can keep possession of, though I want advice putting all those money into buying coins and keeping, that money is large enough to run a blockchain startup from small until it grows to an higher height, so I would advise that you use what is left to build a crypto startup company and I don't think you will ever regret doing it, you don't need to do something big like coming up with a new idea, you can just build on an existing idea and make it bigger and better.
