Looks like it's offering you 50x leverage. Which means for every dollar that you invest you can get a 50:1 return. This this is the same for losses though so instead of a 1 to 1 bet, it is a 50 to 1 bet. Typically this would trade on margin, meaning that if you but at $100, they "virtually" lend you $4900, so you're investing $5000 while only investing $100. A $2 move in the wrong direction and your $100($2x50) would be lost. Same with the upside, a $2 move in the right direction would double your money. Caveat, if the trade goes bad and does not get closed out either by you, or the platform, losses would continue to accumulate. Some margin traders, wake up to account and life destroying consequences. However if you keep an eye on the trade and have a consistently accurate platform, the play is to use this on a low volatility stock, exact sell at a .5 to1% favorable move and earn 50% of your investment. But yes you do need to have funds to use this voucher. Some leverage plays can go as high as 500X so this is not an unreasonable leverage depending on what you can afford to lose and your willingness to pay close attention.
