No, I don't believed that only 2% of American has invested on Bitcoin. Yes I would have to agree that we underwent a big change, from $20K to $6K but it doesn't mean that everyone is going out including the Americans. So this is just another fake news to undermine bitcoin rise to prominence in the last couple of years.

the data is only from a small group and they are investors to begin with so 2% can be a correct value. but it in no way represents  the whole population or the whole world. when you look at a larger scale then it does not even reach 1% and so far the data (which is from 2017) was during one of the bigger bull runs that bitcoin had and lots and lots of pumps, hypes, advertisements of altcoins which attracted investors even for a short time.

Bitcoin creator "Satoshi" has 3 million to 5 million Bitcoins

when the result is 2% having a margin of error that is 1% means 50% error, and 3% means the poll was all wrong!

bitcoin has never lost 50% or more in one day and the drops never came out of nowhere. they always come after a big rise has happened. for example when bitcoin was at the bottom a couple of years ago at $220 we never saw a drop. we saw some panic push-down which didn't even last more than 1 hour which doesn't count as a drop. the drops came after the rises for example  bitcoin went from $1000 to $20000 then it had the big drop over 6 months.

I am just nitpicking about the math though. but I agree with what you said. it is the volatility that makes some people not-want to invest in bitcoin and also the unregulated situation of bitcoin market and also all the FUD.

The thing is not all investors have a appetite for high risk investments, so the figure might still be very low, because people regard Bitcoin as a high risk investment. A lot of these investors are also totally clueless about the technology or misinformed by mass media, so there is still a lot of work that has to be done, to educate these people.

The only reason why some of these investors, invested in Bitcoin was because Bitcoin was the top performing Currency/Commodity in both 2016 and 2017.  

BTC's current price is more than 8,000 US dollars, many people can't afford it!
So 2% of US investors holding BTC itself have already stated that it is excellent!

I would seriously question the 2% figure? I would be surprised if it was as high as that, given that there are about 327 million in America that would mean that over 6.5 million Americans own Bitcoin?

Where did that % come from? and how did they arrive at it?

Seems that the percent must be bit bigger because Coinbase was the most popular app on the app store in January. So just imagine, how many persons bought a bit of bitcoin or another crypto.

Well post some links here on the claim that only 2% of the American investors own bitcoin because literally we do not believe on it when this forum is dominated by english language which means that the people here are mostly the american people or if not then we can clearly identify who clearly had the greatest number or volume of members who engage in cryptocurrency here in the forum. Eventually it does not make sense at all the US government is strictly implementing the cryptocurrency regulations which boasted also the confidence of American people to join and invest in cryptocurrency that includes bitcoin.
