I think the best one for me is Bitcoin. I like Bitcoin a lot. Since investing in Bitcoin can be done with a small amount of money, not a lot of money. Especially if the price of Bitcoin drops, if I hold it for a long time, then I can get good profits from it later. I think Bitcoin can reach a huge price in the future, so I want to hold it. I think if I hold it slowly, I can make good money from it.
And it would be even better if you could raise awareness among those closest to you about this so they too would do the same for their own futures. By these people, I mean the people in your household and those around you who have become like your own family. As more people become aware of investing in Bitcoin, it will also strengthen Bitcoin's resilience and give them the opportunity to share in the benefits. But if they don't want to do the same, that's fine, because I don't recommend forcing them to do this.
