I don't participate in Twitter giveaways at all. I tried before but never got anything and just stopped... the same goes for the chat drops, it used to be interesting to be a part of the chats and get various coins, but it's not like it used to be either. As always, it's interesting at first, it can have some value, but after a while, it all gets boring and becomes irrelevant... you play on a site because you like the games and various features.
i only ever join low prize twitter giveaways as there is a higher chance to win those since fewer people and bots join. i won two giveaways this way so far...
if you get really lucky, you could hit a crazy run from chat rain and even make a withdrawal. but it takes so many tries that it's a literal waste of time.
