Why so pessimistic about the outlook of bitcoins? Now in July BTC is still above 9,000 USD. I haven't sold any of my coins in a while and not going to do so. Bitcoin is a currency like many others, you can use it as a diversification in your portfolio. And historically speaking it has been a good store of value. Storing your value would mean it rises slighty with inflation and doesn't jump around to $20k. I believe bitcoins will become more and more stable in the future, making it a good instrument to save money. For gambling and high risk investing I would recommend altcoins.
Can we just support the bitcoin? Can we just believe on it?
Some people here are very negative towards the bitcoin's future even if the only thing that they consider are its volatility and fluctuation in the market. It is really hard to predict the bitcoins price but if you truly believe on the ability of bitcoin, you will invest to it and treat it as a good store of value. If you want to secure your future, bitcoin can be your way to success on your future errands. If bitcoin reached almost $20k in 2017, imagine if it spike again sooner or later. Don't lose the opportunity for you to make bitcoin as your asset.
