I think that investing in the mainstream currency will be a very good choice. The prices of Bitcoin and Ethereum are very low, and they are slowly rising. I think this is a good time for investment.
Yes I agree, for those that dont have much experince and knowledge it is better to invest in mainstream top of the market coins like bitcoin and etherium. It is much safer this way while learning the nooks and crannies of the game.
It is always better to chose the lowest risk of them all. Also do a lot of reading and research.
