Two friends and I are looking to invest on some BTC. We would like to have our returns go to an offline wallet we have with us.

But I'm wonderin, does anyone offer a way to take the wallet Key and split it into 3, requiring all three to ever open it again.

Would have for BTC to hit a million and one of us to move away quickly

I guess we COULD simply break the string into 3, and each have 1/3 secured away. I've also seen an option that allows us to split it into 3, but only require two pieces to open the wallet, this may be the better option but sadly I can not find where this is done either.

Any help would be greatly appreciated guys! Thanks
