Diversify is my adviceI got blok hive and cash. Sure blok is undervalued even if bitcoin would be at 5000. But its at 16... on the other hand hive raised in total abput 150 million cad, blok most likely moves with 10 million. Kash - well what is it - about 26 million... so blok is the smallest one even though... my main holdings are in blok followd by hive then kash. Now to the drop in bitcoin - you realize its meaningless. First of all coinbase opened bitcoin cash which is up 70:/: today so a lot switched today. None of the companies mentioned will mainly mine bitcoin. Kash is about dash, hive bout ether and blok well we will see. S9 miners are flexible. Futhermore we bust had an exchange go bust due to a hacking attack.
