Just another shady ycombinator product. This is their MO. For instance their flagship airbnb thing pretty much consists of enticing ignorant people into breaking the law (yes, it's illegal to rent your rented place to third parties most anywhere in the civilized world) in order to make a few pennies. Basically the breakdown is, you partner with airbnb, stranger pays you fifty bux to mess up your place while you're away, airbnb collects twenty, you pay 2-5000 dollars in fines a coupla months later. Ycombinator business.

Just on the strength of the appallingly scammy record anything coming out of there should be regarded with extreme caution, but then coinbase/coinwhatever in particular is a pretend-company that took a little venture capital last year, pranced around Bitcoin making taakiesque claims and statements all the while failing to develop anything like a revenue stream or a product of any utility.

They will be running out of money later this year. Show some common sense and use one of the very numerous alternatives that actually work today rather than regret it tomorrow. Just a little PSA seeing how most everyone in the know seems to prefer not to talk about the scum and the noobish and naive get regularly fleeced.
