I hope you have seen eventually because its either going to be that you are scammed, or you are looking to scam someone. Instead of looking to buy below market value, the market itself has created an avenue for one to buy more even at low price with the various price volatility that is being witnessed in the last couple of days which I feel any serious individual should have taken advantage of.
For Op and any other person looking to buy below market value, just have it at the back of your mind that to make that possible, someone somewhere, is getting robbed of that coins.
