the current marketcap is based on the 62 million coins available on the market, which is not the total supply . I've not kept up to date but I think the total supply even after half were burnt is above 700 million AMPS at the very least.  articles reported that half of the total available supply was burnt. that amounted to 731,108,937 AMPs....
ethereum current supply is 84 million ETH. not sure what the total supply is or will be for ETH. I read of about 150 million ETH...so yeah if those are the figures I overstimated the x100. but I think you underestimated.
