I think cash is king for giveaways mate, either that or you could Tip the winners account with money if they have an account with BC.GAME (not sure if 500 have the tip function as i dont have it). Also, I could make you a discord server if you wanted, somewhat similar to what the website does but in my opinion, easier & better for people to use in my opinion. Within the server I can easily make a giveaway channel where people can just click to enter and use a wheel or something to decide the winners. It would be a place for like-minded people, voice chats for people to chill in, private channels that only you and whoever you want to sit in. Would be good for videos as well, you can “pull” people over that are sat in a voice chat into yours and do a bonus buy for them or something! Just drop me a message or a reply if it sounds like something you’re interested in mate. Or message me on twitter @vein444_
