1. It's very much good to know that both bitcoin and gold are nice investments and choosing one over the other is really hard because if I have the opportunity I will proudly invest in both. Let's borrow some ideas from some people who already answered this question, bitcoin is more like a digital gold and traditional gold is the physical one we can see and hold. The two are good investment but if we are to chose as coiners then it will bitcoin for sure.
2. Yes, of course bitcoin is becoming more attractive in the investment sector but this answers is biased because I haven't done any scientific research on that to go into conclusion but as from the informations gather from this forum I think bitcoin is becoming more attractive over and over again.
3. That's solely in the position of the person himself to answer that because I don't know if surely Peter Schiff have accumulated bitcoin or not but we can say yes he must have having find out that it has proven itself over the years and it's still not lost like other scam projects.
The success and attractiveness of BTC does not negate or compete with Gold in the economy or in professional investment portfolios. Each investor and investment fund will have their own criteria for profit and risk, from which they will decide whether to allocate a few % to BTC as a new and extremely potential asset. Although BTC is still very small compared to Gold in terms of capitalization and acceptance, the increasing interest of investors in BTC is a good sign for us!
All investors want to make a profit, and I believe that even the famous Gold supporters would have chosen BTC if they had known 10 years ago that BTC would become the extremely successful asset that it is today. However, we all know that they also have a very high ego, so they will deny BTC until the end of their lives, even though BTC could reach 1M USD in the future.
