I believe Altcoins will experience accumulation through the rest of the year with breakout in the fall and start of a massive bull run. Perhaps they are left in the dust yet again as bitcoin experiences the beginning legs of the bull market. To me this reminds me of a basketball bouncing and if you drop a basketball on the concrete it will bounce and each bounce has a lower high all the way until it is nearly dead on the ground, yet if given energy (fresh capital inflows - profits from bitcoin moving up) it will start to bounce again.
A slow and long bleed in alt coins would really cause a lot of people to capitulate after underperforming in 2019. I could see this happen again, yet in fall all of those losses could be erased in a matter of weeks if not days.
This is for my own reflections as a trading journal and not to be taken as financial advice. I am using it for educational purposes to see how I progress in my abilities and skill as a swing trader.
