I know we wouldn't reach to Goldman Sachs for advise in cryptocurrencies, however we can't deny Bitcoin is on a bubble. We are inflating the bubble with huge sums of money while Bitcoin doesn't really change and improve it's technology at the same rate.
Goldman Sachs advisor says
'Today's Cryptocurrencies Will Go to Zero, But Stronger Digital Currencies May Still Emerge' and this time they can be right. And pretty much is okay to relate today's situation with dotcom bubble back in the 2000's.
I can see two ends for this, whether development becomes a priority and actual value and usefulness are created for the big cryptocurrencies we handle right now, or the bubble explodes. If it explodes then a new type of cryptocurrencies will emerge, although I don't believe these would follow Bitcoin principles.
