Welcome to the forum and thanks for sharing your trading story here. You made well by making profit with $100. I'd like to know why you didn't chose to have bitcoin? is it expensive for you?
And now I'm looking for money to invest more 
Do you have a job? if you have a salary then you can have that practice of buying crypto's once you received it. But if you don't have, I think you can use your skill by creating presentations for such projects.
