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 think that a time span of 4 to 5 years is very long for the crypto space where we usually see a lot of day trading, but as i am a notorious hodler myself i really like your approach. If we assume that the overall direction that the crypto market as a whole is moving will still be upwards because cryptos in general are still very new compared to traditional finance, then i think it is also pretty likely that there are more than just a few coins out there that should or could give you a x50 return of your investment after 5 years. You don't want to hear the big names here so my Suggestion would be to take a look at Lithium finance. They offer a crowd based pricing Oracle and have received Investments from very reputable VCs.
