Recently, I've been looking for ways to multiply the Bitcoins I already have. Because I believe Bitcoin will continue to go up, I don't want to sell my Bitcoins, just invest them for more Bitcoins.
One way I've found was investing in a tumbler service, which you can read about here: https://steemit.com/cryptocurrency/@bitcointycoon/bitpetite-still-paying-4-5-daily
Another way is investing in mining. I am using Genesis Mining right now to mine Bitcoin. This is a great way to generate Bitcoin on a daily basis!
I did try some HYIP schemes, but a couple didn't work out so well, so I decided I want to avoid them in the future.
I'm still on the lookout for more ways to multiply my Bitcoins, so what are you all using to multiply your Bitcoins?
