On ACR Poker Blitz tables dont run 24 hours, and usually the lowest stake, that run, is 25NL. I have only played this game a little bit, since I am mainly a tournament player. But unsurpricingly it seem to be pretty reg infected with russians and other eastern europeans making up a large percentage of the player pool as well as of course some americans.
Definitely not a soft game, but to be honest 25NL fast fold games are hardly soft anywhere. If you come directly from play money games, you will most likely get crushed, so I recommend starting lower and honestly also with normal tables, that tend to be softer. ACR Poker can be a fine choise, and with regular tables there is pretty much always some action at both 2NL, 5NL, 10NL and 25NL.
Depending on your previous experience with
real money poker and your financial situation you could either deposit $100 and start at 2NL/5NL or deposit $300 and start at 10NL. I dont have any experience with Ignition, but as I understand it, its an anonymous site, so you have no idea, who you are playing with. For me personally thats a deal breaker.
