I believe that no investment related to matters of digital technology can be considered as a safe investment in the long term, because the very nature of this technology is precisely to innovate, evolve, improve. Several years ago no one would think that the MSN messenger would disappear, or that myspace, hifive or napster would end up falling as well as the Altavista search engine or the Netscape browser, therefore, I do not think the bitcoin technology is enough to ensure a long and promising future for those who decide to bet on it in the long term.
