I don't have special preference for the specific coin or specific token but I'm just continuously growing my portfolio for sure. This June however there seems no best investment opportunity for me. I will continue to hold what I have in my hand and what I'm investing since start of the year. My portfolio includes IOST, ETH, xrp, SCL and recently got involved with EOS and REM coin. You may wanna refer them for your investment this June if you haven't done it yet.
