I expect for mainstream adoption of cryptocurrency, predominantly Bitcoin, as an everyday payment method by 2023. By ten years from now in 2028, Bitcoin will unofficially earn new global reserve currency status. It makes sense seeing as how Bitcoin is the first true global currency. The total market cap of Bitcoin will be Trillions, eventually hundreds of Trillions. At a market cap of 21 Trillion dollars, the price of Bitcoin will be exactly $1 Million dollars per coin.
