There is a lot of real and good altcoins since then not only in this month of April. Like Doge, BCH, XRP and even the Etherium. These altcoins shown its value increase amazingly. Ofcourse, currently the BNB. Some alts value last month is high but all of a sudden become devalued this month.  For me, to find a good to be true alts, we have to be more observant, resourcefull and read more about the alts that you are going to buy or invest.
