I'm currently into BTC investment. Regards gold, I don't have any practical experiences, because I have never found an opportunity to start investing on it. It doesn't look an accessible investment when compared to Bitcoin, in my opinion.

Of course. Bitcoin has a much superior potential of profitability, while gold works more as a stable asset to maintain your money value along the time. Both are efficient against inflation, but Bitcoin has an additional advantage due to the fact it gets highly valuable on long run, although we still have to consider the volatility factor which usually plays against investors on short run... Anyway, I guess the decision of investing in gold or Bitcoin will really depend on the objective the investor has for his money: to maintain the patrimony stable or to grow it exponentially.

That is something we can only speculate about. I believe there is every kind of people in the world. There are those who badmouthed Bitcoin genuinely believing on what they were saying and there are those who badmouthed Bitcoin in front of the cameras, while adopting it on the backgrounds. The most important thing is to never get too influenced by these personalities when choosing what to do with your money. You don't have to put all your eggs on the same basket, so why not try investments which these people despise? Maybe they are wrong and your intuition is right...
