Until now, cryptocurrencies have not been suitable for use as an actual payment tool: blockchain transfers have many problems, and they are impractical. However, the emergence of Ethereum-based crypto tokens has completely solved this problem. They are used just like casino chips, but they can contain a smart contract and be assigned to a particular person. It is possible to convert crypto tokens to other currencies (fiat or crypto) on exchange sites at any time. They offer practical use, are safer, work on mobile devices and reduce infrastructure costs. In 2021, we will be able to pay with crypto tokens on more and more bookmakers.
