Is it possible to make incredible gains from even small amounts of crypto?
Absolutely.
What follows is a particularly fortunate and spectacular example of how I like to do that.
XPD is a cryptocoin called 'Petrodollar'. 
XPD had a nice base to buy from with the obvious risk being it goes to zero. Previously I'd noticed the nice triangle in the middle and accumulated shares along the baseline expecting a price spike at the apex. My usual procedure is to place multiple tiered sells above the market price and it worked out well. All my sells were filled for a very nice profit.
More recently I noticed another triangle approaching apex and bought again. Given the higher triangle I expected more upward pressure and joked to myself how funny it'd be if it approached the high on the far left edge of the chart. Just for laughs, I put a sell order in just below that ridiculous spike high. Instead of putting in the other usual tiered sells I got distracted by surrounding household events and forgot all about it.
Days passed, someone mentioned XPD in a troll box, and I checked it out. Literally while I'd been sleeping XPD had spiked about 40X my cost basis, executed my sell order, and then plummeted back down to where it started from.
When things like this happen people typically say 'Oh! You got lucky!' and I absolutely did. However, I wouldn't have gotten lucky if I hadn't placed the sell order above market ahead of time. I would have awakened to discover I missed the entire move instead. Or I'd have furiously placed an order in intraday real time only to go unfilled then sat there trying to figure out how 'the whales' had screwed me not realizing I'd screwed myself.
How many people buy XXX coin and expect it to 'Moon!' only to end up holding it after it crashes back down again?
If you want to 'Get lucky' and you want to take profits find your set up then create your luck by placing your sell orders (multiple tiered orders may be ideal) above market when you buy the coin then forget about it. Instead of looking at one coin obsessively throughout the day and week cheering it on use the time to find another coin with an ideal set up then repeat the process. While others are buying the spike then panicking while it shoots back down again you'll be booking profits in your sleep.
To tell you the truth this story about my XPD trade is a story about a screw up. I should have placed tiered orders in case price didn't go as high as in a ridiculous moment I dreamed it would. By not selling in tiers I screwed up and I did get really, really lucky I didn't end up back where I started.
Is this a recommendation to invest in or trade XPD? Absolutely not. It's a crap coin. The odd thing about this particular point in time is even crap coins are getting caught on a bubble and floating to the top of the cesspool.
So if you really want to take profits find a coin with a set up, buy, and place those sell orders, even the ones on the 'Moon!'.
We do seem to have a base in the 12,500-13,000 zone that seems to be a 'make or break' area. I expect it will reveal its intentions some time around January 3rd. It's good to have ideas about what we expect a market to do but it's fantastic to have lines drawn in the sand to let it prove itself to us.
