It's impossible to imagine the value of the blockchain and crypto currencies, so I'm a long-term investor at this point. I think the value is in my process, not the instrument that I'm trading.
Two, I'm not going to let any one security put my trading process in jeopardy. I've talked before about what I look at and how I rake the data to include instruments within my trading system. I'm not going to change those rules for any instrument.
I have not traded bitcoin futures and I won't be in the near term. There is not enough data and I don't know who has basis risk. It seems like the market is dominated by speculators and not hedgers, and they are heavily biased long.
When the market is lop-sided and fickle, it makes for a poor trading environment. That's why I'm invested and not trading at this point. It's too easy to lose money when I'm trading well...
The best that will happen is that I'll add it to my system and trade it among all the other instruments that are in there. It's not getting any special treatment, nor am I going to try to develop a dedicated system to trade bitcoin.
Use cold storage for your crypto currency investments - that means offline.
You can use a USB drive and drop that into a safe deposit box.
You can also use what's called a "hardware wallet" such as those below instead of an online wallet and exchange such as Coinbase or another online digital wallet that can be hacked.
Lastly, keep your mouth quiet about owning bitcoin or any other valuable cryptocurrency and how your store them. No one needs to know your personal business. Don't brag or bring attention to yourself (about bitcoin, art, or collectibles) so you don't tip off anyone to come and rob you.
