I am just curious why you need to request others to buy Bitcoin. Because you can buy Bitcoin yourself for any amount. It's not necessary to buy a full bitcoin. So you don't need to think about the 50/50 scheme when you intend to invest in Bitcoin. I assume you don't have enough proper knowledge about how Bitcoin works. So you need to study a bit more. I will advise you to spend more time on the forum and read as much as you can, especially related to Bitcoin technology. It's true that if you can't take a risk in crypto, you won't be a gainer at any point. Crypto isn't for panicky people.
Exactly, this is the reason why there are still regrets especially to those who are hesitant to invest because they think they need much time to jump-in but the reality is that they are missing the opportunity. Even when my first time in crypto I am skeptical in investing Bitcoin as well but I am doing faucets as early as I think that was 2014 but still has gained nothing good that changed my life and I have already learned from that mistake because in crypto the early we jump-in the higher the chance we make huge gains and yeah we need enough knowledge before jumping into something risky.
