One more thing I should say, with regard to statement that "blocktrades is only bridge", by which I think you mean that when someone sells a coin to us, you expect us to then sell the coin soon after. It's important to note that this isn't how we actually operate.
We don't have any automated selling that takes place when someone sells us a coin. Many times in the past, when someone sells us a lot of coin, I just hold it. If you don't believe it, you can just watch our accounts, you will see that there is no such automated selling.
To some extent, BlockTrades functions as a "contrarian investor": when other people are selling a coin we will often just accumulate what they sell to us because people often "panic sell", and vice-versa, when they are buying we often will let our inventory of that coin decrease (except we have to keep enough to continue selling it) on the theory that people will often buy a lot when their is a lot of FOMO and the price can rise too high because of the excitement, so we wait until excitement dies down before buying back into the coin.
But in the case of BTS, once I decided that things were going badly, I made it a policy to avoid holding too much, so whenever anyone sold us a lot, I would generally sell it over the next couple of days, to prevent losses as the coin continues to drop in price. Until I see some change in the way BTS is being handled, it's the only safe thing to do I think.
It's not the first time I've made such a decision, of course. There were some other coins where I didn't like the way the coin was behaving, so lowered our inventories of such coins to avoid losses (nushares comes to mind). Sometimes this is just temporary decision: when SBD was much more than $1, I thought it wasn't reasonable for it to be so high, so I kept our inventory low until the price came back to around $1.
