Some time has passed and I have experienced one more weird thing that BitGo wallet makes. That is another warning to those who is using BitGo wallet.
I don't think this needs a warning. I can see why they did this, and (depending on circumstances), it makes sense.
Maybe this is all due to me being inexperienced enough, but I cant understand and find it weird and unfair, that while doing a transaction from wallet A to wallet B, BitGo add to transaction something extra.
Here is an example of TXID. I was sending 0.0031 BTC but into that transaction BitGo has added 0.011 BTC.
It looks like this wallet avoids creating small inputs. If you would have used only 0.00335 BTC to send 0.0031 BTC, you would have ended up with an input smaller than 0.00025 BTC. By adding another input, you end up with one larger input instead of a small and a large one. When fees are low, that's actually a good thing to do. And considering the fee was 1.012 sat/vbyte, it's a cheap consolidation and your next transaction pays a lower fee.
If you don't want this (for instance for privacy reasons), you should use manual coin control. I don't know if "BitGo" supports that.
With 1 sat/byte 0.0031 would be transferred much faster than 0.0141 imo.
Unlikely. Miners pick the transactions with the highest relative fee (per vbyte) first, and the total transaction size doesn't really matter.
So a warning for those who wants to use low fee and expect speed - dont use low fee, as you might wait days or weeks for confirmation.
Again: it depends. If you're not in a rush, a low fee is fine. Check
Johoe's site for instance to see what you can expect.
If you're in a hurry, you should indeed pay a high enough fee per vbyte.
Not to mention that you can send all of your balance. After hitting "max" button, you still have something left on a balance. If you have 0.01 BTC, you can write manually 0.009 in amount windon and use 0.0001 for a fee.
It sounds like you should just switch to Electrum, where the "Max" button works as expected.
