I just want a Core wallet that wont stutter when I open it.
Then buy yourself a capable system and an SSD to run your Core client on. I have done the same, and it works absolutely flawlessly. It's a bit of an investment, especially compared to HDD prices, but it's worth it.
OP:
Calm down and let the market find out what it want. It's pretty safe to say that no one here has even a slight clue of what's happening other than the market potentially consolidating.
If you hodl your coins firmly, you won't lose anything. People seem to panic over normal market activity, but there is absolutely no need for that. I actually enjoy how supply and demand are battling lately.
Each time the price seems to get dumped down, and people think it will go down further, the demand makes sure the market goes back up again. Trade these price swings, or just keep hodling.
