Just like Ethereum Neo is a safe coin for long term investment. For almost 1.5 year the price of NEO has been at a very low point.
NEO's peak was $190 in 2018.
That's the past, and at this point, NEO is only trading at $11. I think this coin is old, and very few investors choose to buy, so instead of buying NEO, I would choose a better investment. The 2017 time period was the best time for all investors because all altcoins at that time increased, and some coins helped a lot of investors get rich. However, after that period of time, the market continues to correct, and the bear market is staying with us.
