Take a look at ETH and BNB. I advise you to invest in this Altcoin, talk about the reasons why you should use ETH or BNB of course both of which are most in demand by investors and the price is also affordable. If you have big capital invest in Bitcoin in the long term. if you are not interested in Bitcoin then ETH and BNB as bitcoin alternatives. I think it suits you.
These two coins are more worthy of recommendation because the fundamentals as the top 5 big coins are very potential compared to other altcoins, I chose to add more BNB at this time because the price is still low and it will be $1k in the future.
