First let's have a look at number of daily unique users and total daily transaction counts on both Bridges. Currently users and transaction on Wormhole are minuscule compared to Terra Bridge mainly because Terra Bridge has always been reliable and well established.

Currently, there has been a total of over 27K addresses that has used bridges; either Terra Bridge and/or Wormhole. Since Terra Bridge has been here for much longer time, we can see that over 95% has used Terra Bridge exclusively while only 3.48% using Wormhole only. Less than 1% of those addresses that used both.

Table below shows all the users who had made transactions on both Terra Bridge and Wormhole. Let's take a look whether they completely migrate to Wormhole or still using both. We will use two addresses; terra1r...wfs2 and terra1v...4uht (Rank #2 and #4 by Total_Tx) because these two have frequent transactions using both bridges.

As we can see from two bar graphs above, both users used both bridges exclusively. I believe they used different bridges for different purposes.
