I personally prefer to hold bitcoin and ethereum. They are good coin and more potential to hold for long term.
I think your choice is right and the same as my choice which so far has always trusted Bitcoin and Ethereum for me to keep for the long term for more than a year.
because in my opinion both are potentially profitable and always provide a good return if we wait patiently.
Why do people choose only BTC and ETH? I think there are thousands of new options right now for everyone and every day I find posts like this that make me boring. I think if you want to make a bigger profit then you should find a new project to invest because these are projects that often attract a lot of investors. In fact, if it is a coin with good technology, it will definitely increase the price very quickly and you will easily earn a profit.
In my opinion, choose some new coins such as ATOM because this coin only appeared last year and the current value of the coin has increased by more than 4654% so take the time to search before you miss the opportunity.
Because most of here are bitcoin aspirants. Cryptocurrency live because of bitcoin and ethereum. These two pioneer cryptocurrencies need to be acknowledged also since they developed the crypto industry.
Yes, there are many alts around here but some of them have fake volumes, slow development and unfinished products.
