Linkif you have an iPhone click here and sign up for Metal Pay. You need to use a referral link in order to get their current $25 bonus(mentioned here). Click the link and click the download app button. After you register they’ll give you $25 in Metal Crypto(might take a half hour or so).

Once you have the $25, click the Crypto card in the app, then click “Metal MTL”. Click sell and enter something around $24. The Value of metal is variable, so you’ll need to enter less than you have to cover the transaction cost and the current value. Enter the amount you want to sell and click sell and you’ll have the cash in your account. You can now withdraw your cash to your bank account for free. You can close your account by contacting them and opening a support ticket.  Valid only in these states at the moment: AK, AZ, AR, CA, CO, DE, FL, IN, IA, KY, ME, MD, MA, MI, MN, MS, MO, MT, NE, NV, NH, NJ, ND, OH, OK, RI, SC, SD, TB, UT, VA, WV, WI, WY, Puerto Rico and US Virgin Islands.
