I've done lots of posts about this subject on various threads but I'll sum up some of my thoughts in a very condensed format this time.
Common sense is about 80% of trading.. buy low sell high.. don't get cut by falling daggers... don't fear the blood and view it as an opportunity.
1) If you buy at the bottom of a cycle, there is no danger in your position.. its established a bottom price and usually can only go up from there.
2) Most people who try to do TA do so in what's commonly called the "dumb zone". You cant play 30-50 sat moves on a daily basis going all in or all out and expect this to work.. thats not really a strategy and will break down.. you're almost luckier if it breaks down the first few times you try it so you won't try it and get really burned when it really matters or learn from the wrong thing and really screw up when you add more money.
3) Prices that something has reached before in sats is much easier to achieve a second time over trying to predict unproven highs.. buy LOW and take the easy money.. wishing welling prices is just emotional and will not help... if you buy tron at 300 sats.. expect the easy returns to be where it overcorrected.. don't hold for unproven all time highs.. if you go 100% into profits on something you better be selling some. Whales don't care about your long-term goals and will dump on you in a heartbeat to get you to lose hope, panic, and sell to them waiting at the bottom again.
TA is the other 20%.. it helps you min/max your positions by making smarter exits/entries..
Sell below fibonacci retracement resistances and ladder out.. sell some and participate in almost any runup, but save some of your bigger bags to sell at higher prices,. don't go all in or out, just set goals and zones BEFOREHAND so you won't get caught up in fomo or fud.. 80% of my trades happen when I'm not even paying attention.. I set ladder buys and sells on things I'm interested in and it all just orchestrates itself... If my bags get too heavy towards alts, i dump some bags earlier.. if I'm getting kind of skimpy selling upwards, I can become more risky with top exit points.. it should always be a revolving door of covering the top and bottom all the time, no exceptions.. no all in alts 100% ever.
Here is an article I wrote this more in-depth, and talking about the types of TA i use... but like i said TA isn't gonna really do much for you if you don't understand market cycles, avoiding emotional stimulus, and generally buy at the wrong times.
