Harald Seiz, CEO, boldly made that proclamation on his public facebook page a few days after his world tour concluded in Miami on Oct 21, 2018. Currently 1g of Karatbars Gold costs about $65.00 - a great price for kinebar grade gold. On Golden Independence Day, July 4, 2019 you will be able to exchange 100 KBC coins for 1g of gold.
OK, so how to calculate your percentage gain:
So that's a nice 40-fold gain on your bread on July 4, 2019.
Furthermore, the explicitly stated 5 year target is for one 1 KBC coin for 1g gold. That represents an additional 100-fold gain in value over the initial 50-fold gain, for a total 5000-fold gain. That means those same 100 KBC coins acquired now would be worth 100 grams of gold 5 years from now. Using the same market values for 1g gold and presuming the US dollar is still around 5 years from now, $1.30 would yield $6,000 in 5 years.
Roughly $200.00 of KBC now would be 1.2 million dollars worth of gold in 5 years. And because you are dealing with gold it doesnt really matter what happens in any nation's economy because gold is a medium of exchange in every nation and every period of time for mankind.
Visit the KBC coin listing on Coinmarketcap and click on Markets and then buy the coin on any exchange listed. You will need to obtain Bitcoin from somewhere and then send it to the exchange to make your purchase.
