KMD is a good choice for you to buy it and hold it at this moment,
because in the next few months later,there will be an atomic swap.
also other than that i think SEMUX has a lot potential.
i think for now the most appropiate crypto to buy as long as there are much money to spend I'll go for ethereum as it is the most leading token that has a bigger value than others and have a big potentiial that in time to time will many times the value than today.
