If you cant see Bitcoin is in a bubble then you need to give up trading. After a drop price always makes a massive rally to make all time crazy highs, this is just to condition people into holding onto there Bitcoin when price crashes again because now they are conditioned to thinking price always goes up! One time in the near future this is going to happen where price crashes and doesn't go back up making the people at the top even richer and the small people will lose everything.
In Bitcoin there is no value at all, you can only make the money other people lose, it is a massive pyramid scheme. Some larger traders have entered Bitcoin positions which has pushed price up to draw more people into buying before price dumps. Bitcoin almost has a cult following, and we all know how most cults end up.
I could go on all day about why Bitcoin WILL fail but i wont. Feel free to message me if you want to know more.
If you has knowledge of the 4 year cycle you'd realise that while speculative to begin with Bitcoin has now become a hedge against fiat inflation which of course is not backed by anything tangible but has intrinsic value because our governments tell us they do... and even less value after 10 trill of QE. We will see pullbacks of up to 40% but that does not detract from Bitcoin's long term use case. The only threat to BTC is potentially China and the FED.
