You are right that in many years the regulation will change and we do not know how it will affect the projects, but that risk will always exist until the governments regulate it.

to all Fud-ers crypto is not the space for you to hang out 

you can't outright ban a transfer from one wallet to another. at best they'll require you to fill a KYC at the exchange, which you can easily bypass in my experience.

There are some bad news regarding cryptocurrency especially ICO's things recently. It looks more and more countries trying to make this kind of investment harder.

okay I did not knew that - how does ether delta handle this?

To protect US citizens from losing money through scam ridden ICOs, the SEC took the measure of disallowing its citizens from joining the bandwagon. Right now the route to buying tokens is a bit circuitous. Swipe your card through an exchange like coinbase or changelly for ethereum or bitcoin, and then you go ahead get the token. For etherdelta, you sign-in by syncing your etherwallet. Not the safest route ever.

I don't recommend using etherdelta - lately they allowed substitution dns server, as result were stolen various tokens cost of millions dollars.
In the case of decentralization, no one is responsible for this.

It can be dangerous too, I know some cases when the tokens were stolen not from exchange market but directly from the wallet. anyways, do your best to secure your capital and hope for the better)

Yeah, or exposing your private information (e.g. private key) to third parties by mistake or as a result of fraud. As far as I know Linux or MacOS is more preferable than Windows in terms of security
