I will suggest that never put money in new coins because there is no guarantee that will these increase or become low. If you want to trade and desires to earn money then ethereum and bitcoin are really good coins to put some money. There are large numbers of people who have earned money by investing in these two.
The new token does not guarantee about its reality, may be these new tokens are scam and all of your money become zero. Some new originated coins does not remain for long time, they diminish after sometimes.
If you want to put money in new coins then just first investigate about them, about their liquidity, volume and many more but just start from a tiny portion of cash.
BTC and ETH both undoubtedly safe to invest at any time but why peoples investment on other new projects because they need early profit which is not happen in BTC or ETH. New project is always risk because i have seen 90% is scam at end of the day right now.
