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.
I suggest ADA to be included in the list of potential coins you are looking for, if you talk about the long term, this coin has shown its quality, you can see on the coinmarketcap rankings where this coin is able to reach the fourth rank in the crypto market.
