1. Bitcoin value is all based on sentiment. Most people say it is under valued now, but that is only a reflection of how you feel about it. And this is fine, because in comparison most stock prices are irrational as well (especially these days). people make lots of money buying over valued stocks. But the problem I see is that the fear-of-missing-out sentiment has passed. Almost everyone know about bitcoin now. And they also know Bitcoin has dropped 70% of the value since its highest peak? Once someone get burned by something, the others will be a lot more cautious. And when people become rational about a investment that is built on sentiment, that is a huge problem for future growth. there are many examples of puffed up stocks crashing down to earth, and never to recover its value. The ones that can recover and soar in the long run all have great business fundamental to support its value, in other words "making money".
All that's required is for one endorsement by a country a company or a large group of people. Because the sentiment
is the driver...and when people become rational about their sentiment they will jump in when they hear some positive rational news.
Almost everyone may know the world "bitcoin" but hardly any people know why the rest of us believe bitcoin is valuable, is better than something that runs our lives. Some education on that front could change sentiment, or the strength of it.
2. Bitcoin is no longer unique. Regardless of what people say, bitcoin is not like gold. Sure, the amount of bitcoin is finite, but it is not unique compared to other cryptocurrency. The only thing special about it, is the name itself. And there are tons of new cryptocurrencies now, and people can create infinitely more types, IF it is profitable. Correct me if I am wrong, what is the fundamental difference between a "bitcoin" and a "ripple" other than the value? nothing at all.
The fundamental difference between bitcoin and ripple is that ripple is private, owned by a company (of the same name). Ripple is not an open source network from which anyone can begin mining and participating. Ripple has a business plan, a marketing plan, they thrive on deals they make with financial institutions. When you buy ripple you're buying an investment.
Bitcoin is more open and free than currency.
3. technology risks. There is always a possibility a more advanced cryptocurrency will emerge and completely outshine bitcoin. I believe there are already some cryptocurrency that transact faster than bitcoin? Not sure of the detail but I have read it somewhere. And when it happens again and again bitcoin will be wiped out. Remember we used to use CDs? tapes? camera films? Bitcoin was created almost a decade ago, that is a lifetime ago in the technology world.
Evolution is real. The reality is that there is no other cryptocurrency...that is intended to be used as a currency (this eliminates Ethereum, Ripple, a few others)...that is more well known or has greater adoption as bitcoin. So, yes, other cryptocurrencies can evolve what Bitcoin offers. But cryptocurrencies also allow easier speed to evolve through hard forks. If Bitcoin is to become obsolete, we're no where close it yet.
other issues: practicality, and safety. It doesn't actually make paying for something easier, and some argue this is safer than traditional banking, well just look at the news of people lost coins or got hacked.
It does actually make paying for something easier, but more accurately it makes transferring money easier.
If you need to pay a friend or a significant other, why must it take 3 days to get paid? It's ridiculous, it's "snail mail" in the age of email. It's 1980s technology. Inter bank transactions should be instant. Cryptocurrency offers that.
Companies like Venmo provide the illusion of instant payments, but if you wanted to move that money out of their app it would take 3 days..they're spotting people the transactions because they can keep control in the app.
I do think it is possible for bitcoin to go up (not skyrocket though), but it seems the headwind is getting really strong. So why do you think you should hold on? Instead of just saying "it will go to the moon", "it will change the world", please provide reason.
Bitcoin still represents a much needed better alternative to a system that every one of us must use.
There's incredible opportunity to improve upon the financial payments system. There's an incredible number of people that uses the financial payments system (like in the Billions of people). Those two things - opportunity and market - equal a good recipe for investment growth. For revolution. It won't happen over night, but it will happen...with Bitcoin or something that is derived from what Bitcoin started.
