Just go to their website https://karbon.io/ and scroll down a bit you will see contribution address for both ETH and BTC on their page.
Anyone can convince a gullible fool. So who cares if you spoke to them. What matters is whether this project can make money. If they can provide projections and a detailed business describing exactly how they can return gains to tokenholders with a sound justification for the amount of gains specified them i stand corrected.
You claim to have a deep understanding of ico business models. Ok, then name me one ico that has a unicorn valuation from a tier 1 investment bank and is about to be listed on a reputable exchange such as nasdaq growth segment or nyse mkt. Don't get me wrong flipping ico's in the short term is great strategy probably the best way to part fools from their money into one's bank account. But your joking if you think most ico's have long term viability. I can probably think of four crypto start ups that have a chance of making good money for founders and coinholders in the long term.
I don't attack projects because i am bitching out. I am just expressing my opinion. My opinion is focused purely on the monetary aspect of things not subjective rubbish such as whether the founders seem honest, nice or dedicated. I dont care if the founders are a bunch of c*nts. I care only about a businesses ability to make money.
If you can highlight how karbon can make significant amounts of money with its current focus then i will withdraw my criticisms of the project. if you are unable to do this, it proves you really do you really do not understand business or are simply a shill. Investing in a successful business requires much more skill than simply flipping an ico.
Considering the ico market is in a bubble anyone can make money flipping ico's. Idiots and short term traders are throwing money at ico's regardless of the viability of businesses model. The amount of fools fawning over this project despite the lack of plans for monitization makes me think this is a good coin to make money riding the wave of a pump and dump. A good flip nothing more nothing less.
