I've seen some restaurants and business that are accepting bitcoin and cryptocurrency as a method of their payment but I didn't try it because it's not worth it to pay for things and food for your bitcoin because of the high transaction fee.
For me it is just matter of time when more and more comporation and people will try to make their business available for crypto, after that it will be just easier to make people believe in this market.
People doesn't need to have a convincing strategies to make them believe on what principles did you have. This business in crypto was always depending on each respective decisions, that has strong desires which makes our asset grows evenly. The trust can be developed by making our community strong, and it doesn't guarantee to have the assurance if every holders will be greed for money. There should be patience in every aspects of life specially on business matter.
