As a trend indead Bitcoin has really show it's potential value, as in case of society currently are about to change which will automatically make both investors and government agencies to change their currency into Bitcoin inorder to safe guard their money it is a note that there are every probability that in time to come cryptocurrency will be officially adopted
You should never tell someone what to do with their own money in crypto world. You can show them the benefits and if they are smart enough to understand the potential, they will invest on their own.
And about the post being here, it's the bitcoin forum man. Everyone in here is somewhat connected to cryptocurrency. If you really want people to join the crypto community, then spread these words where people don't have any knowledge about it. Interact to people in a manner that those who haven't heard about crypto can learn about it and get interested.
Here's small advice for you. Tell people to always do their own research after explaining something and for you, never trust anyone on the internet before verifying that they are legit.
so I encourage everyone to go into cryptocurrency either in terms of trading or investment.
You may encourage someone, but if they don't have proper knowledge about either trading or investment. It's a total loss and in the end they will blame you. So teach them the basic of crypto first, then move to the next step.
For example, if you have done your own research and analysis on price movements, then you can give them a hint on which way the market would move. If they can make some profits, only then they will be more interested to stick to crypto.
