Thanks for the info @jonesteemit
But it is more unlikely for bitcoin to crash in near future. Because there are a lot of fiat money trading against bitcoin. This is used for other crypto coins to get fiat money. But since the emergence of ethereum, people are started to use ethereum instead of bitcoin in order to get fiat money.
This is my reading. Of course using technical analysis together with fundamental analysis will give you more accurate picture.
You are right, bitcoin need to solve their transaction issue in order to remain attractive.
Thanks again.
