I think that the most important thing we could do at this stage is to educate the general public about bitcoin and other cryptocurrencies. We could start with:
1. The philosophy of bitcoin/crypto
A lot of people think that bitcoin was created only to be used for illicit activities. With all the exaggerations of the mainstream media, that's what most of my acquaintances believe bitcoin is for: paying for drugs, laundering money etc. Everyday we hear on the news that a crime lord has been arrested and that the police confiscated x hundreds of bitcoins from him. When I tell them (my acquaintances) about Satoshi's vision (and not just that, there is a lot of philosophy regarding other coins), most of them come to the conclusion that they have been deluded by the 'sensationalist' media. They actually find cryptocurrencies quite fascinating and want to start using them.
2. How to use bitcoin/cryptocurrencies
There is a great percentage of people in the world who can barely send an e-mail, or who simply don't know know how to use a computer. Using cryptocurrencies is for them the equivalent of rocket science. Good guides and courses should help in this area.
3. Raise the awareness regarding crypto scams
A lot of beginners get scammed these days, so that their enthusiasm turns to rage towards cryptocurrencies. Some start to think that everything regarding crypto is a scam and discourage other people from using them.
