No strategy, but only luck, makes you win the lottery. And winning the lottery will be a one-time event in your life.
I have some experience in the lottery, joining different platforms, but honestly, I haven't made a good win. Buying more tickets increases the chance of winning, and I hear many gamblers do this. But I don't think it's a good idea to adopt this kind of idea when we are just having fun.
I guess it's all fun and games until a whale decides to buy all the tickets, just to get that euphoric feeling of winning, and ruins everyone's chances.

Although I doubt any billionaire would even bother participating in a lottery.
Anyways, Rollify has now also added a new feature that allows their users to buy crypto directly from their platform.
How? Log-in, go to Wallet, then
Buy Crypto tab.
And with that, they also rolled in a $100 prize to those who would try this new feature. Not quite clear how many would win, though.
