Although it is true that technical analysis applied to cryptocurrencies is very fragile, and you can not establish the real value of the Bitcoin using this tool, I do not believe that a trend line projected using historical information brings us closer to the real value of this type of digital assets.
I strongly believe that the value of Bitcoin (and altcoinsin general) is strongly linked to the advantages and disadvantages that these have in relation to fiat money and the financial system in which they operate.
And above all, I think the real value of bitcoin is shaped in large part by the contributions that this asset generates (or will generate) for society. By this I mean combatting hyperinflation, corruption and financial exclusion.
