Almost four weeks have passed, some guys need to close their positions after 28 days so let's have a quick look how these imaginary individuals are doing today:
First guy, miner, went and bought that gpu and is adding it to his rig today. He is -$400 on cash and is holding hardware worth of $300. Estimated mining profits $1/day and he is back where he started from in 100 days.
-$400 on cash, hardware worth of $250-300, mining profits $1/ day so currently somewhere in $278-328 range total. Loosing money so far but this miner still believes there are better days to come and keeps on mining.
-$100 in four weeks, this thing isn't going to the moon.
Second guy, investor, went and bought 0.083 btc @$4800. He is -$400 on cash and is today holding btc worth of $475.
-$400 on cash, holding BTC worth of ~$620.
+$220 in four weeks, looking good.
Third one, trader, opened a leveraged 5x long position on btc/usd. He still has that $400 (tied to position) and his position today is worth of $775.
$400 still tied to position, now the time has come to close it. After expenses he now has $1,450 cash,
+$1,050 in four weeks. Probably better to sit down and do some thinking. One thing is for sure, he's not going to buy more gpu's.
Just some food for thought.
Happy mining guys!
