Here's a guide for Monese & Trading212. Takes around 20 minutes together and will net you a £10 bonus (with Monese) and a random free share (from £5 to £100) with trading212.

First sign up to monese here: https://monese.app.link/G8ZHFcZ5YW?invite=SHIVE869 code SHIVE869

Now click card and create a virtual card. To get credited with £10 from Monese you have to make a transaction with the code. Top up your Monese with £1 by sending £1 to the sortcode/account number.

Then make a trading212 account: http://www.trading212.com/invite/4FWnQkD

Once you've made it deposit £1 using your Monese virtual card into an INVEST account on Trading212. That will count as the Monese payment.

Trading212 will give you a free share that you can sell in a few days, then Monese will credit you with another £10 bonus within 24 hours that you can immediately send back to yourself
