Why I will wait for Bitcoin to go below USD 1500

Bitcoin or any cryptocurrency is not a solution to any problem in its current stage. The valuation of Bitcoin today is hyped up by certain individuals to make it sort of a Pyramid scheme to make quick returns.

What is a 'Pyramid Scheme'
A pyramid scheme is an illegal investment scam based on a hierarchical setup. New recruits make up the base of the pyramid and provide the funding, or so-called returns, the earlier investors/recruits above them receive. A pyramid scheme does not involve the selling of products. Rather, it relies on the constant inflow of money from additional investors that works its way to the top of the pyramid.

It does smell like it and tastes like it....

Bitcoins or for that matter any cryptocurrencies valuation cannot be just based on an idea it also has to have cash flow supporting it as well.

Bitcoins value derives from it acceptance (Because you think it has value). This can be a dangerous proposition as a downturn can nearly wipe out such a valuation if not supported by fundamentals.
