For me i choosed new altcoin that just entered the market a feew week ago that has good fundamentaly and has working product like POWR, VECHAIN, WABI, DATA, AION. My prediction the price of these coin will be going up in the longterm because they have unique project and the purpose of the project is very interesting and also different with others.
For me if I want to invest in cryptocurrency the first choice will be bitcoin and the second will be Ethereum because these are the two digital currencies which lead the crypto world.
Most of the people are investing in bitcoin, ETH, LTC, Ripple because other cryptos are no place in the market and they have no value for the investors. Therefor nobody is investing in more currencies. Bitcoin and Ethereum are the best to invest your money.
