donating

I'm just looking for the best way to set up donations for my channel, I would like to have this system be able to be integrated into stream alerts, and I use YouTube to stream. If you have ways to set up donations like different websites and whatever I would be glad to hear them :D

I want to get a donation button on my YouTube but I'm not sure which would be the best option, could someone help me with this? I have paypal at the moment but the amount I can receive in it is limited so I would like one that isn't limited. I have looked at Patreon but obviously being in the uk...
