What are your goals when investing in new coins? Did you get a huge profit from the new coins? Can you recommend a new coin worth investing besides LUNA?
Altcoin investment is good if the coin is a little bit more trusted meaning it exist at the long period of time in the market. ETH coin can be trusted coin but all the price is of course always fluctuates. But i can say that ETH and BTC are good choice of investment specially if it is at the long term.
