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.
many people will definitely recommend bitcoin, ethereum and bnb because these coins have the potential for high price increases in the future. if in the timeframe you want for 4/5 years then these coins will go up fantastically. but if you don't want bitcoin, ethereum, doge and bnb then I will suggest you to buy Cardano because I believe cardano will continue to increase every year and you can see the history of cardona's growth on coinmarketcap as a reference.
