Hello, multifunctional platforms based on electronic and crypto wallets, such as trustchange, are one of the most reliable ways to buy, exchange, sell and store cryptocurrencies. For example, crypto wallets, unlike exchanges, do not store cryptocurrencies centrally and are much less susceptible to hacking. Such platforms usually receive licenses and operate as financial institutions, having the full right to work with fiat and provide clients with various financial services, including transactions with digital assets (cryptocurrencies).
