I have received some ambs in my wallet, but I want to know what is the ratio of the AMB and Ambits, I have got 240 ambits, but there is only 1735.2 amb. It seems that 1 ambits=7.23 amb, as far as I know, 1eth=1000amb=300CHF(approximately), that means 1 ambit=2.17 CHF, far from 1 ambit=5CHF as mentioned above, so why there is a difference?
