Bitcoin Price Struggles to Leave $4k Consolidation After Upside Push

Bitcoin (BTC) has again retested the important $4,000 price ceiling on 19-20 March, but is unable to remain above this level on non-Tether exchanges.

Instead it has continued to range in the same consolidation pattern that began after the 16 March breakout. This consolidation appears to be a bull flag, between roughly $4,000 and $3,940.

However, the price is holding at or above the 55 hour EMA, which has been trending upward. Respecting this line (below, in pink), appears to be another squeeze within the $4,000 resistance level. Volume was rising on the 19th, but has dropped off again today (20 March).


The support / resistance (S/R) zone in the low $3,900’s must be held in order to stay in this consolidation. Should it break, however, there is a strong knot of support at mid $3,800, as well as the Feb-March uptrend support (in green, below) to catch Bitcoin’s fall.


In the long term, the area between $4,100-200 remains key. At this scale, Bitcoin is consolidating within an ascending triangle pattern, which is bullish. There is plenty of elbow room to manoeuvre, but this pattern could continue for months. Should BTC break out, it would quickly be in striking distance of the critical 200 day moving average. Getting and staying above the 200MA could change the long term trend of Bitcoin and end the bear market.


On the very long term (weekly chart), Bitcoin is approaching a level of downtrend resistance. A failure to break this could be problematic. What’s more, it is hard to ignore the possibility that on a very long term, Bitcoin has formed a bear flag, suggesting the possibility of (hopefully) a final capitulation to end the 2018 bear market in style.


Error in Time-Locked Bitcoin Contracts Allows for Miner 'Fee-Sniping'

  • Crypto researcher 0xb10c discovered an error in bitcoin "time-locked" transactions that could be used as an attack vector.
  • Miners can take advantage of the program to carry out "fee-sniping" and steal funds from one another. 

Users have discovered an error in bitcoin “timelocked” contracts that could potentially allow miners to steal BTC from one another. 

Anonymous crypto engineer 0xb10c reported discovering more than one million “time-locked” transactions made between September 2019 and March 2020. In a post, 0xb10c detailed how these special bitcoin transactions were not being accurately enforced by the network. 

As opposed to normal transactions, time-locked transactions prevent recipient bitcoin from being accessed after sending. Users must wait for a specific number of blocks to be added to the network in ten-minute intervals before gaining control of their bitcoin. 

0xb10c claimed the errant time-locked transactions provided an attack vector for miners to steal transaction fees  from one another via “fee-sniping.” According to the engineer, the backlog of time-locked transactions were being purposefully designed for a “potentially disruptive mining strategy” involving the theft of miner fees. 

In an interview with CoinDesk, 0xb10c said time-locked transactions represented a “low-priority” problem at present that could eventually balloon to involve the wider network. He explained that fee-sniping would become more lucrative in a few years as the majority of miner income shifts towards transaction fees. 

He continued, 

A fix for this has been released in early 2020. However, it will take a while before all instances of the currently deployed software are upgraded.
