1. Bitcoin
Yep, that's it. Bitcoin is all that matters. Investing in 99.9% of cryptocurrencies, especially in the long term, is worse than investing in penny stocks.
Indeed bitcoin is a reliable crypto to invest for short or long term. Its proven to be profitable and less risky compared to altcoins.
However its good having alts too in our crypto portfolio, I have eth, bnb and iost.
You can hold whatever coins you like as long as you did your research because we are using our hard earned money to invest so better to be cautious.
While BTC is good, there are other projects too that are cheap and can potentially earn 100X times than holding a fraction of BTC. Most of the time they say its only BTC that matters but when it comes to making a profit by the time of bullrun, its always those cheap altcoins that will make you rich. Holding some altcoins isn't so bad when they are among the top 50 coins.
