very good portfolio bro, because bitcoin and ethereum are two giants that still have very good opportunities in the future, stay HOLD because the gems are already in your hands 
all obviously not going to ignore what you say mate, that bitcoin and ethereum are by far the best in crypto and will continue to be so in the future and it is unlikely that any will be able to overtake them if you look at the market capitalization to date.other than the already held HOLD, it would be wiser to continue buying and increasing the investment while the price is going down.
