We need to create new methods.
As TA is just pseudo-science for speculation, we can trace lines from anywhere and say this is mathematically reasonable, just to provoke bull-runs and push the price even higher. The more people buy, the better. Bitcoin can solve money problems for lots of people. Imagine governments hoarding bitcoins to pay debts to the banksters.
Depending on where the blockchain technology is going, people can even stop working and automate everything, generating money from solar panels, and earning it during leisure time.
But there are some disadvantages too that factorize the whole Bitcoin system to be unsustainable - Problems of blockchain size, problems of higher number of unconfirmed transactions and problem of fees - these were the 3 major things why we decided to support Bitcoins and now these things have become a problem.
Blockchain size - needs to settle down because if you have a PC with just 80 - 120 GB hard disk, you can't even think of downloading the whole blockchain for your desktop-based wallet.
Unconfirmed transactions - I don't understand if miners are intentionally doing this to let the fee be remain raised like nothing for free (or less) any more.
Fees - The above explanation refers to this as well.
But yeah, Bitcoin is not the same any more and I think that the way we used to follow those patterns has nothing to do now with what we are seeing because observations need to change with the change in numbers that are already changing at a higher pace now.
