At present, bitcoin prices are down at $ 6,644. This is a opportunity to buy bitcoin for long-term investors.
But still need to be careful as the downtrend remains. The reason for the bad market may be due to an increase in access bans for international trading sites in China and the number of banks prohibit credit card payments for cryptocurrency
It was a great time to buy Bitcoin even for a short-term investment. But if we are talking about a long-term one then I think any buy below $50k is a good buy.
It doesn't matter for what reasons Bitcoin went down this time because there always will be some "reasons" for going up or down since BTC has always been a highly volatile currency and it will remain this way in the foreseeable future. Imo it can become stable only when all the people who can potentially have it will have it, but we are far from that point right now.
