I invest and hold, sometimes I try to catch some tops and to sell at that time, so I can buy more coins when the price dips! I learned everything by myself, I had a headache from all the readings, from trying to learn about something totally new for me, from trying to apply all that in real practice, sometimes it's not an easy task to apply everything you learned...
So my investment strategy is my own, it's hard to describe it in a few words... but it works for me, and I am not sure it will work for others! What is unique for all of us is the learning part, trying to apply that and practice it with real money, and in the end, to find what suits you, your time, and your bankroll is important, as the part "how to do it" and be profitable in the long run! Try to learn and to find the best for you! It's my advice for all the people who are ready to invest themselves in crypto!
Learning on your own is definitely a good idea knowing you have all the resources then so there's no reason you can't do it. You don't need to rely on someone else as the crypto market is full uncertainties so better explore the market ands discover on your own.
I usually go with the market trends and all that goes that hype in the market as long as i know it has high potentials to gain huge demand and the utility case is there. Its just that lately i'm more attached on NFT's projects because of its usefulness so people are definitely rushing into it especially that its very profitable this time. And of course i'm still into hodling my most potential coins with bitcoin and ethereum and some top altcoins that are heading into their new ATH in less than 3 months i guess.
