Value is that of a 1 gram (5 carat), UNCUT diamond, which is around 100$. So far i have 50 grams of diamond.
Thank you for your opinion.
50 grams of diamonds? how many coins will you make? 50 gram diamond backup funds will not be enough if you make millions of coins / tokens. the value of diamonds is not different every type and shape?
If you are reading the main topic that has already written by OP and you will see if he has already mentioned it, OP said that if 1 gram of gold will equal with 1 gold token but i think if that doesn't make sense consider diamond cost a lot of money.
