When they 20x, I will take out 2x of my original iñvestment and If they 50x I will take 50% of my iñvestment for the next bull cycle in 4 years.
You mean "If" they 20x. I can't think of more than a handful of altcoins that I actually see appreciating in price over time, and especially inside of 4 years. Usually, a market takes time to grow, unless the coin is specifically used for pumping, and dumping which is not something that you particularly want to invest in if you believe it'll reach 20x, as very few altcoins actually do this.
