High risk ...and a real novice move
What happens if you have a buy in @ 330 and it only hits 331 (this has happned to me on many occasions and to make a point I missed getting filled one time by 0.4 cents )I missed where the OP stated that he was buying back in entirely at $330.
Dont do that! Buy in in tranches FFS!
Back in March on the crash to $400, I had dreamt that Bitcoin would rebound off $380 a couple of weeks previously (I place a lot of faith in my dreams when I get them). Thus, I placed a 60 BTC order at $391.34 (every penny of spare capital that I had to throw at Bitcoin). I missed out on the bottom with my entire order by less than $10. By the time I got out my bed, Bitcoin was already back up over $500 and I had totally missed out on what might have been a 13K profit within 2 days, but due to my shit trading skills would have probably been just an 8K USD profit. As it turns out, I got fuck all except 1K I took on 20 BTC from $490 to $545.
Always buy in tranches!
