Re: What is the most critical moments in Cryptocurrency and Bitcoin history
I remember cryptocurrency in December 2017, could make heart attacks, high levels of panic and stress
01. Most Painful
I accidentally deleted the private key and password to enter the blockchain.info wallet after 1 month I completely forgot the email address listed on blockchain.info, 02. Happiest 
I got lots of new friends in the Cryptocurrency business and was happy to see bitcoin prices increasing in 2017 but in January 2018 it was very painful. 2018 is very painful but that how the market is going to be, we have to be very patient in order to make most profits. Cryptocurrency becomes very popular in the year 2017 due to the price of Bitcoin increase very high.
