looking at the exchange charts.
   IE:  i see where the wave hit. depending on the coin...     i look at chart 6months back.(year if i can)  whats the high/low.   (also using the buy/sell numbers from before for myself ..as my memory sux)
if the high was 100 and the low was 60...    my numbers are 90 and 66    (10% each way)
obviously, its rough.   and each persons would be different.    

if im more into the coin...     i might push higher...

if its a more 'stable' coin.  my numbers would be tighter.

   but ALWAYS inside of the waves.    (like a surfer! lol)

what kills you the most.  Greed.

(and its subtle)

    hm.. if i just wait a bit more, my numbers will be a bit higher....ill make a bit more...ill     then bam. its dumping.

    i've learned that lesson.     i still have panic moments...   thats when i walk away lol.  omg i just bought at 990 and its dropping.....     wait. its ok.  its pennies...

my 'panic sell' at that point...is setting the sell at 1000 ish.     990 * .002 =991.98  (exchange fee.   then withdrawal fee if you go that way)    so i look at 1000 as even.

then walk away.

background:

   I started with MEC gifted to me.   $5

got me hooked.  lol.

i bought a Falcon (27mh/s scrypt) lost there.    some gridseed pillboxes.   8 something on btc   (plugged in first one, and it smoked...)  still have the rest.
(my fault)

   then..lets see...i think i built a computer rig with some Radeon 270's     then 280's  (vertcoin!) before they switched.

So, i was far under profit. lol.

started exchange more...and did alot better.  (enough that i thought i would try again at mining:  S5 antminer.  i broke even on that one!  i was amazed.  (i didnt expect to when i bought it)

Did  mined Verge/gld and dnote with the falcon btw.

Did well enough that i bought 2 L3++, which are doing well. (already paid for, just in HEAT) lol.  its frigging cold here.
  I have them both 'listed' to rent.  which is interesting.

(i'd share the link here, but that seems so.....cheesy)
pm me for that and i guess ill give it out that way.

as Verge rose, i sold off some here and there.  mining more...and so on.     (pity i sold a bit too much, when it was alot lower lol)   but i still have a nice chunk.

*edit   I GO a bit wacked here.  so I delete




How do you calculate the buy and the sell number? (If not secret)
