Now that I’m 18 and have a fair amount of money from my salary, I’m directing it towards Bitcoin investment, and other investing projects.
Good to hear that, I suggest you to learn about Bitcoin personal wallets and also about cold wallets before investing in it. Don't ever leave your Bitcoin at exchanges as that's the worst one can do with his/her Bitcoin. I'm pretty sure that by investing in Bitcoin you'll understand the benefits of it. I suggest you to follow DCA + Dip buying strategy.
