If we recall back in 2014, there were very few ways one could invest in Bitcoin. Most of which left people feeling insecure of were where they left their money. At the same time, most of us even thought Bitcoin was the only "internet currency" out there, and was only used by criminals on the internet.
Well here we are halfway through 2017 and just about everyone you talk to, has at least heard of Bitcoin and/or Ethereum. This is primarily due to media, and how accessible it is. Instead of people having to go to some sketch site on the deep web in order to invest in Bitcoin, people can now do it easily online from their desktop or phone. Companies like Coinbase, leave a feeling of security after purchasing their first bitcoin. For the first time in history your parents and grandparents can easily invest in the world of crypto. For the first time cryptocurrencies have officially gone mainstream, we have banks, companies, and governments looking to utilize the blockchain. This is not the same as 2014.
So I believe this is not a bubble. Instead, we have established an entirely new market cap.. Which will likely undergo a healthy correction, to establish a new stable growth line.
Thanks and Good Luck All!
