did you miss the chance? one can buy at 4500, once it breaks 4900, it will rally to next the level.
Please look at the charts and see, how the price moves. Hits resistance (Fib levels or any levels), then price pushed down to previous support, gathers support and breaks the resistance. If resistance is strong, it is tries for 2-4 times and breaks it.
So the same is happening with ADA, 5000 was resisted well, price pushed down to 4500 levels, it is trying to break the resistance. Once broken, sellers would turn as buyers and they will push for more price.
2500 --> 5000 100% in 2 days. Hold for more. Note BTC fall may impact the coins.
