I like the video it is so educative !! For me i have no bitcoin now !! I have only altcoins and some great cryptos that have lots of great potential and future like : Litecoin , Lisk, Cardano , Siacoin, Iota and many others. Bitcoin is so slow it is Like a nokia 3310 lol.
Bitcoin is the father of all coins, it’s not going away.... once lightning is widely adopted and proven to be safe....it will double or triple in price. I won’t would never count bitcoin out.
