Anyone trade Bitcoin or any crpytocurrencies? In spite of me, one of my wife's relatives thinks he has money to gamble with. So was looking to inform on appropriate brokerage (if that's even a valid term for trading crpytocurrencies).
The one place the relative mentioned was Kraken. I know that's name of some monster. Didn't want him land with the TDAmeritrade for cryptocurrency, so thought I would ask here if anyone has a recommendation on who to go with.
