The title is a bit silly really, it suggests that bitcoin will have its next period of stability around 50k, that means that we will pump all the way from 13k to 50k without experiencing any stability, I don't think such a period of pumping can happen now. from 1.3k to 5k it didn't even happen and that was a much smaller increase in terms of real value despite being the same in percentage terms.
Bitcoin price will be 100,000 end of this year(2018)
50.000 is very small amount.
