People like warren buffet can't say things like this. Because what he says applies to every coin in the world, a coin doesn't produce anything, but you can sell it, and in exchange you will receive something, because everybody believes that this coin has a certain value. And that is the challenge, make the people believe in the value of bitcoin, not to produce anything

Warren Buffet has never been a fan of gold, he doesn't like gold as an investment, preferred to buy shares of a profitable company.
Because he thought that gold is lack of utility, requires storage space and security fees which isn't a productive asset.
Note it; Warren's company Berkshire bought roughly 20.92-million-share purchase of gold-mining stock Barrick Gold, he bought the share of a company, not the gold.

Let the Old man Release His stand since Days are coming for Him and in the years come may gone completely while Bitcoin and cryptocurrencies will remain here.
And besides never that we can expect good words from Him towards our community here because there are no chance that He will change course from using other platform to profit than crypto.

As crypto enthusiasts, we can ignore him.

FYI, Warren Buffet is the 7th wealthiest person in the world.  With his age and the types of industries he invested in, obviously, it will be hard for him to understand the value of Bitcoins (that's why his a Bitcoin hater).  When he mentioned that "you don't do anything with it except sell it to someone else" the statement is already wrong, for all we know even a piece of chewing gum that you sell for a single cent or a penny still has a value which made his statement incorrect because anything in this world regardless if it is physical or not and you are able to sell it that means it has a value which confutes his own words.

Anyway like OP said everyone is entitled to have their own opinion and be able to express it in his own way. Just ignore him he might just live during the stone age, IMO.

your right everyone has a point of view but its hard to accept when a famous personailty talks negative towards btc .

he isnt just famous but he also known in the financial field , with the knowledge and expertise he have on this area , its almost impossible that he didnt study btc before he gave comments in public .

 is this the guy that had a dinner or lunch with the tron founder before ? why he did do that and he also recieve a crypto gift which was btc and some tron from justin then later on he came out with this sentiments 

Warren Buffet doesn't really hate bitcoin or cryptocurrency. Warrent Buffet is just avoiding it, because he knows the future is in blockchain technology and not in cryptocurrency. Warren Buffet doesn't understand why a platform without an underlying asset can have such volatile prices.
Warreny Buffet also said that bitcoin could not be valued because it was not an asset that gave real results and basically bitcoin was just a mirage.

Even so, bitcoin still has its fans because indeed bitcoin is a future technology that has the potential to continue to be developed.

Trick or treat!

Besides, Warren has made several mistakes in investing, mostly neglecting the investment because of misunderstanding or little information which I consider safe for him, though his misunderstanding does not affect the success of the project. As crazy it might look for everyone, neglecting investment for little information and misunderstanding is still very vital in making investment decision.

I really don't care about what Warren buffet thinks anymore about bitcoin or cryptocurrency, that's his own opinion and choice everyone is entitled to their own opinions, since his already old what do you expect old people don't really like learning new things, same way most of them have no idea what crypto is, so he can continue saying bad stuffs about it as long as he wants, for me crypto is the future, there's no way I'm gonna leave it, because Warren buffet doesn't like it.
