A child grows and develops over time....slowly. If the child was 7 feet after his 1st birthday (even his 6th or 7th), you'd definitely wonder what's going on. I have no doubt the crypto markets will be worth much more than this in the future....however this instant growth boom is purely based on greed and speculation as most blockchain projects people are trading haven't even been developed or being used widely. There's nothing fueling more demand besides prices going higher and people getting greedy. In finance, these patterns can't sustain. In 2013, people (myself included) said the same things that it wasn't a bubble and everything and then look what happened. It WILL come back down.
