According to CoinMeta, Czech commercial banks Partners Banka and Anycoin have collaborated to integrate Bitcoin into their customer fund management applications. Customers can open Bitcoin accounts and start trading from as little as 500 Czech crowns (about $23), without having to pay any custody fees. There is a 2% transaction surcharge, of which 1.5% goes to Partners Banka and 0.5% to Anycoin. Petr Borkovec recommends that the allocation of Bitcoin in a portfolio be limited to within 5%, and the product currently does not include other cryptocurrencies.
