Traders viewpoint:
I suggest, you should have actual analysis base on facts and concrete evidences that will show a fluctuation of trades, otherwise it is all bullsh*t. There are long game e.g., 40% Long-Term, 25% Mid-Term, and 35% on-hand currency for quick flips. If you are looking to capitalize on small percentage gains (1-10%) by trading a lot with a decent amount of bitcoin, there are coins designed for just that purpose (do your research). As for those short-term 5,000%+ gains, ironically, that requires a bit mid-term strategy. I do not usually advice putting a bunch of coins on these all at once; you will likely lose your money or scare off the pumpers. Accrue gradually with small amounts that will not make the price fluctuate much and keep in silent, the more people you let know about it will likely smashup your investment, best to do these so you know whether it's stable enough, observe.
If you see pump activities, put more on right price before it takes off. When those coins that are going to sprout up in the next couple of days, most are nearly impossible to tell with more than an hourly notice, you pretty much have to stay ready and always observe the markets for coins that were not on the radar beforehand. Remember to never set single sell walls; divide it up on multiple prices, the lower the amount on each price the higher probabilities you have of it being sold. Try to stay under 0.10btc per price on high volume coins and 0.05btc on lower volume coins, might suggest spreading them out deliberately for you to regain your original investments early on and still have free coins to play with.
