It is believed that what you have sacrificed for is dear to your heart. We all want the worldwide adoption of cryptocurrency but until we make personal sacrifices, it is still far fetched. You can makes sacrifices like educating people to fully understand cryptocurrency. Reading from social media alone is not enough to convince people until they see a friend or relative actually testifying about it.
I think that a common thing which many investors have sacrificed for the growth of the cryptocurrency market is time. Honestly, I had dedicated my lot of crucial time in this market. Be it for understanding it fully or making my relatives understand it, participating in forums, etc. so I sacrificed a lot of my family time, weekends when I used to go on some small trip, etc.
