Evidently you show another somewhat pragmatic (and just as valid) view to the situation regarding cryptocurrencies. It is a reality that BTC is a value as absolute as gold and that it can be susceptible to manipulation in terms of its price, however, both in its issuance and technology human intervention is null, therefore it generates more confidence among users. On the other hand, unlike gold, BTC does not require large expenses in storage and safekeeping, if you keep your cryptos in your possession along with your passwords you can hardly be a victim of a hacker, another thing is to keep them under the care of third parties. Greetings and thanks for your comment.
