Bitcoins I only buy with quantum atlas, since they do arbitrage in the 4 biggest brokers kraken, poloniex etc ... this yielding approximately 18 to 35% annual gains are variable, the atlasquantum and one of the only ones in the world to do arbitrage with bot and a very safe company. about Swiss bank I was going to open account with cim bank but they ask (income tax declaration) for that reason I declined, but I opened easy account in bank Dukascopy and Swissquote easily online and documents by DHL and both sent me card, these two banks are more to invest in forex and︀ you have a card to have access to money more easily, and they have other︁ products as well
