If this works so well as you claim, you should atleast afford the copper badge to increase your trust alittle on this forum.
so far i see no user availed on his promtions so there is no proof if it is really working but i dont think that there is no such thing as making money no matter what is the outcome , like the op said . buying a cooper membership wont also increase his trust .
As far as it is a way of making money, it much involved risk. There is no risk ways in gambling. If you are investing in bankrolling you are still taking risk as it is still very much possible to lose your money.
yes i agree on you but why there are still other users here that says arbitrage has no risk ? in this world everything has a risk imho , how much more in trading or gambling or on everything that money is involved
