Bitmex allows multiaccs, so it's possible to manage 4-5 positions manually (more than that will be total mess). But I see some challenges with this method:

1. It's not easy to open high-leverage position (otherwise it's not worth the effort) in such volatile market
2. You need to manage positions every day, because you can't miss opportunities to place "soldiers"
3. Crypto infrastructure is immature. It's risky to hold long term positions 
4. Capital. You need it. The author of the method was already successful entrepreneur at that  time, I think it's crucial to be relaxed about losses. 

However, I think one can overcome this and fly not to the moon but to the mars.
