If the company is acquired, a number of things could happen. It's important to note that for the most part, the company doesn't control the coins. They simply publish a contract that provides for the tokens to function, but normally the administrative capacities of such a contract are limited once the sale is over. When administrative capacities do exist, they are typically controlled by one or more people controlling a particular private key. The owner of that private key will have control of the contract, so in order for a company transfer to transfer control, that private key would have to also transfer. (they'd probably want to redeploy the contract under a different key anyways since there would be no guarantee the old owner didn't still have a copy of the old key.)
Say people paid a company called Microhard $30 million in Ether during their ICO for Microhard coins. Can Ether be readily be exchanged for $30 million USD?
Assuming it can, and Microsoft acquires Microhard, and has no interest in crypto doesnt this leave a coin on the market with a name of a business that doesn’t even exist?
The trade volume of Ethereum was about $400,000,000 in the last 24 hours, so likely yes. Bitcoin and Ethereum are the two most popular cryptocurrencies.
>Assuming it can, and Microsoft acquires Microhard, and has no interest in crypto doesnt this leave a coin on the market with a name of a business that doesn’t even exist?
Yeah. That coin's value will probably drop fast given that its value was probably based on the anticipated value of it once its supporting product existed.
