What was that quote or saying... "the more personal the experience, the more universal it is".
You're not only one that who got burned in that darned "Crypto-Winter of 2018".
Lookin' back and zoomin' out of the BTCUSDT chart... it was one big-ass correction (aka. one big friggin' "price markdown" a la Wyckoff) then a long-ass Accumulation till now. The upthrust... that's just test to shake off weak hands (those darned bear short-sellers) out of the market to bait us to buy and raise the price so that they could sell it off later. Whew!
