You are either crazy or simply performing money laundry, you suck at both, instead go like this;
Buy whatever you can afford to buy.
Open BitMixer.io and send them 10% of your bitcoins and give them an address no matter what address.
Sell whatever you receive in Kraken and then send another 10% until you are all done and then go to sleep knowing you are in the clear.
People might scare you by lies and misinformation, better not pay any attention to them.
Not wanting to be tracked to exchanges or service wallets has nothing to do with money laundering.. Your BTC is eventually going to go through a fiat institution if you want to use it as currency in most of the world.. Everything from prepaid cards at the local dollar store up to a broker account has a identification requirement and is reported to the federal government in every country..
One of the things that's always annoyed me about this community is how people will catch grief for things like this, but pre-mined alt-coin authors and half-arsed casino and niche owners nobody bats and eye to.. People here even quickly forget about site owners literally leaving with millions of USD worth of BTC inside a couple weeks(who usually go startup again and repeat)..
