For me the most stressful part of exchange trading is the psychological stress from checking hourly for price action and having to wait a long time because you don't know when the next high or low will be. It's also extremely frustrating to call the highs but not have orders filled, so if you are gonna be placing large orders on altcoins then I suggest choosing a high volume exchange where you can get a lot of liquidity, or better yet: multiple exchanges for maximum market depth. I invested into doge because I was afraid of bitcoin breaking sub-6k, but I think that until doge gets its ETH bridge, it will stay a pump-and-dump market with bearish action after each dramatic price surge. Every time I note a trend or pattern or indicator, it vanishes within days. What annoys me the most is how some days doge follows bitcoin 1:1 and other days it completely ignores bitcoin fluctuations. I hypothesize that doge dumps are a reverse-indicator for bitcoin pumps, and that panic in the bitcoin market is a positive-indicator for doge pumps.
