for me i'm prefer to investing all my in a part like this :
50% all of my fund are invested in Bitcoin
30% in Ethereum
20% invested in BinanceCoin
this is just my personal speculation, because the fundamental the coin above is really strong and the coin/developer are trusted with support from community at all
yes you are very right and I also like your investment list. especially is bitcoin, I always prioritize investing in bitcoin. then the second step with some of the top altcoins like ETH, EOS, BNB, LTC. to minimize losses when compared with new coins or old coins that are difficult to develop.
