Betting via an agent might be a good solution for you then. I am betting nearly exclusively via agent accounts and never had any problems. You don't have to share your details with the bookmaker then, with some agents you don't even need to share your details with them. This agent betting has grown into a big business the last years.
First time hearing this, not sure why would you even want to hire an agent for this but maybe it's your own prerogative. But to be honest, since most bitcoin gambling sites do not even require ID or a KYC policy, then I don't see the reason why you have to get an agent. I've been betting on sports on bitcoin sportsbooks the past couple of years and never had problems.
Most Bitcoin-only bookmakers have shitty odds. Then you have bookmakers where you can deposit/withdraw with Bitcoin and have good odds, but you have to do KYC (Trofo don't wants/likes KYC). Via an agent you can have it all: Most competitive odds on the market (1,98/1,98) with high limits, no KYC and Bitcoin deposit/withdrawal.
For me personally I am not able to bet with a lot of bookmakers, because of georestrictions. But via an agent I can bet with all these bookmakers/exchanges like Pinnacle, SBO, Maxbet, Singbet, BetISN, Betfair etc. Agent-Betting sounds a bit shady, I admit that, but the agents are making tons of money, so there is no need to scam there customers. In Asia, where the big betting money is, betting via an agent is just a normal modus operandi. I've never heard of someone getting scammed who played by the rules.
And it's really easy, you play directly f.e. on the Pinnacle website and only you can access your account. You deposit/withdraw via the agent and the agent charges some fee for that (they can earn some more money with you, but YOU only pay these deposit/withdrawal fees)
