If you want to be a millionaire, you've to stop trying to get rich quickly, stop searching for a single investment with 100x. Start as small, slowly accumulate and grow your fund to a certain amount where you can stay holding for a very long. A long-time holder with ease, no pressure or anything force you to sell your bag.
Only then, you'd hold a coin for years and make a huge return like 5-10x of your investment. That's where you'll be a millionaire, a good coin that you can hold for years.
