There has been an interesting change over the last few days.
A few days ago all users in here responding to my posts were extremely angry that I would even suggest that there might be problems with Bitcoin. But over the last 24 hours, there has been a change. Now I more and more see:
- people who agree we are heading into a bubble (altought different views on when it will burst)
- people who agree that miners are increasing transaction costs dramatically and are a threat to very idea of decentralized Bitcoin itself
- people who have lost money due to various hacking scams
The tide clearly seems to be turning
The first point you mentioned is purely speculation and regurgitation. People read something they know little about and then spit it out as if they were experts in the field. Technically speaking you can't attribute a stock/asset to a bubble without it crashing. Until then its purely speculative which has no underlying foundation.
To address the second point I don't think it's necessarily an over-dramatisation but rather just an indicator of how big this scalability issue is. Changes are needed, that's for sure. The only issue is finding a solution that everyone can agree on.
Regarding the having/scams, what's changed recently? The USDT story only broke the news a few hours ago. Hacks/scams are more dependent on the users. If you know what you're doing and exercise caution then you coins would be safe. It's more about personal responsibility than anything else...
