Understand market signal? Are you mean TA? and invest on any new token? Its trading since you're more focused on TA and pump-dump new coin. Most of new coin on 1-3 month will have huge dump and become worthless, only few token can survive in this scheme. While invest is you need to understand more about FA than TA, also the length is between 6 months - 5 years.
Both of invest and trading must need hard work and experience. You need to control yourself and not be greedy.Trial and error is pretty common regarding trading, so its why experience is very important!
I definitely agree with Jawhead999 here. Trading != Investing.
The skillset is totally different IMHO. For trading you need a decent understanding of financial market, TA or coding skills (mandatory if you are a quant/arb or just want to fetch data from an API but I think it helps in general).
Conversely, an investor who focuses 5-10y from now must possess product knowledge, understand the long term competitive advantages (stellar team, winner-takes-all markets etc.) and formulate educated guesses on how a specific industry may evolve in the future.
Very different games.
