I did some research on Bets.io and found the following:
Bets.io operates under the Curaçao eGaming license.
This type of license is very weak, doesn't impose real oversight, and doesn't protect players.
It also allows the casino to apply its terms as it sees fit, so practically there is no entity to which you can effectively file a complaint. In other words, this often means you have no real protection.
Trustpilot User Reviews:
You'll find mixed reviews about Bets.io but there are clear complaints about:
Account freezes and Balance deductions and Withdrawal problems
https://www.trustpilot.com/review/bets.ioThey have a Anjouan licensing.
That is even worse, an Anjouan license doesn't impose
any oversight, nor does it provide any player protection whatsoever. You won't get any help from there.
In bonus related issues, AskGamblers rarely sides with the player. Most likely, your complaint will be closed with the conclusion that the casino "acted in accordance with their Terms and Conditions," as those terms are generally very vague and often include a clause reserving their right to revoke any bonus and associated winnings. Still, AG is your best bet on retrieving those funds. Just don't expect much.
In general, I'd advise playing against bets.io or any related site. Even if they don't outright confiscate your balance, they have a tendency to delay withdrawals for months by asking for KYC documents, review it for weeks, then ask for more, rinse and repeat.
Edit:
I mistakenly assumed that the term "LOW RISK STRATEGY" referred to bonuses, as it makes no sense otherwise. However, it appears they are using it in the context of sports betting...
First, there is no section in their ToS titled "LOW RISK STRATEGIES." The cited Section 11 is titled "ANTI-FRAUD POLICY." I assume they consider low-risk betting to be fraud and are accusing you of it. And what is low-risk betting? Anything they say it is.
In the end, it doesn't really matter, whether they pay out or not is still completely up to them.
