I've joined plenty of signature campaigns that promote gambling platforms. I tried all of them since I'm curious how good their platform is. All of them are user friendly and I doubt that you can't handle those because it was made for any gambling users even if you aren't a techy person. I'll recommend the signature that I'm wearing right now, not because I'm a participant of their platform, you can check my recent posts and already bet plenty of btc on their site, very easy to use and there's also a market bet for politics. I also recommend other such as freebitco.in and roobet, made some review about them because they have a lot of minigames to play.
I'll second this. Again, I'm wearing the Futuur signature, but again, you can check my posts and see that I've already been betting a lot on the bitcoin markets. It really is an excellent site - and I'm not being paid to say that! It's early days and some of the markets are quite thin, but it offers a lot more than traditional sports betting, with markets across business, science, entertainment and politics - as well as the facility to suggest your own betting market. And if you're unsure about putting bitcoin on the line, there's also play money markets so you can test the site out.
I concur. Gambling sites that has signature campaign here in this forum provides a decent gambling platform, they won't promote it and have a signature campaign if they are not confident about their gambling site platform. Besides, checking out gambling sites that has signature campaigns gives you an assurance you need that you're safe and your funds as well while you are playing, no need to google it, just look at the Services thread and you could see a lot of what you're looking for.
Always gamble responsibly.
