If I don't care on spending lots of UTXO in one shot, reusing addresses, mixing coins, coinjoining etc., that doesn't necessarily mean that Bitcoin is bad for criminals. Lots have been caught and it's generally not a good idea if you're going to do something
really bad, but it depends from whom you want to hide. Is it your wife or your employer? They aren't going to find out much if you use Bitcoin. Is it the government? You're screwed.
However, I read that those two kept the private keys of the 119,754 BTC to a cloud server. I highly doubt they were cautious enough. Also, this doesn't make sense:
I think the transaction the Government cannot track in the block-chain technology has not be made.
Just wondering on why they havent done lots of ways on mixing out those coins so that they wouldnt able to be traced up considering that there are several ways on mixing your coins
without being caught but well its just right that they are just dumb enough on having no consideration on making those things and thats the reason on why theyve been traced up.
