There are so many top altcoins available in crypto market. Those are already hundreds time pump from their tokensale price. so there are less chance, those top coins could pump again 40x to 50x (although some are exceptional)

Please don't throw Ether, bnb, doge names blindly (some people always suggest btc eth bnb everywhere)

Now kindly suggest some altcoins those have potential enough to grow 40x to 50x within 4/5 years and Kindly explain your logic for supporting those.
