I think people will use bitcoin if the governments and banks would consider it as a valid means of payment. Meanwhile, all we can do is trading on the exchanges like CEX or Coinbase, buying and hodling (

Attracting them in terms of this type of opportunities will lead them to gain interest, as of now there's only few establishment who really cater the actual usage of this cryptocurrency, we need more involvement coming from institutions and businesses to attract more people to take some consideration to
adopt tis chain, using investment means is very effective to invite them and make things reliable for them.
