I would suggest to you the bitcoin and ethereum is very promising coins it is good for the long term investment, these coins are continue rising up their prices through the years this the best for investment for the newbie investors.
not coins that continue to increase. bitcoin and ethereum also experience ups and downs. this is indeed the most suitable asset for long-term investment, but stay alert to surprises on the market.
Investment certainly has risks, the higher the profit level, the higher the risk and vice versa, investing any coin is always at risk even bitcoin is number # 1, the market is always unpredictable because of full decentralization.
