I think there is no better altcoin than eth, i also prefer some top altcoin that you can see in CMC, there are a lot of top altcoins there that you can choose. I also didn’t invet in new projects there are a lot of scams and i feel unsafe you can follow CMC or coingecko for the top rank altcoin and do investing base on your own pick don’t be dependent on other suggestion choose it by your own because at the end of the day you will be the one to get loss or get profit by your invesgment.

When it comes to future or long term holds then better stick with bitcoin and other top alts like ETH or in top ranks and dont look for something new which hadnt really able to get some popularity and recognition in the market but i would tell you this that you should
always remember that nothing is assured in crypto investment.

Dont put your life savings on it and always remember about the risk involve on crypto investment which basically means that only make use of the amount that you can only afford to lose.

If you are really eager with new altcoin investment then make out some better research.Look for project relevance and usability rather
than on investing into something due to pure hype and shill.
