Honestly, the fastest way to collect BTC is to gather enough information on where you might get it in an easy way. One of the fastest ways is engaging in this community where you will learn a lot of fundamentals and how bitcoin works. After that, you will need to join some of the paid campaigns to get yourself your first BTC. then from that point, you can start holding your earned BTC till the last payments you recieved.
It's almost impossible unless you are in a campaign which pays like Chipmixer. Chipmixer pays near 2 BTC per year if someone post maximum. How many other campaign pays you 1/10th of Chipmixer. Almost not at all. Signature campaign is just an extra income, it can never bring you a big balance. Also, It's not possible for people who promote signature here to hold without spending, only very few people can.
