I agree with you because BTC can change a person's economy, especially for people who invest in 2017 early who are very sure they have got a big profit, I myself actually got a little extra funding for my life because of cryptocurrency. I did a campaign bounty and so on which produced coin coins, little by little changed my economy, and indirectly it was caused by cryptocurrency too 
We've seen and read some of the testimony about the Change of once life after participating into crypto currency investment (Bitcoin). during the same period last year until the end of that quarter Bitcoin is on the news, people had earned millions of investment on the very short period of time, yet sad to note that there are also people who dive to invest without learning the market and suffered so much because of the wrong timing of investment. So, i would say yes, it maybe true to some people who learn the process of investment, and i feel sorry to the people who didn't learn the market prior to their investment into Bitcoin...
