You don't even need to hide anywhere. Since there is no regulations on pre-mines themselves, only ICOs, you could do a pre-mine in the US and be 100% fine as long as you paid the capital gains tax.

IANAL, so take this with a grain of salt.

Meanwhile, I'm holding out for the day ETH crashes, ICOs end, and pumpers go back to using Litecoin forks. I'm just sitting here with a GTX 1060 ready to mine some scamcoins for lulz.
