Altcoin has just finished a classic (see white Fibonacci levels). This is a strong support indications. The price came down to support on a large candle on extreme . This is called a selling climax and is, in this case, a sign of trend exhaustion. Bears would probably struggle to push price any lower.
These signs indicate the bears have had their say and the bulls will likely take over. A break below 458 would invalidate the other signals and suggest bears are back in control. Otherwise, there's plenty of upside.
