When you see many positive news enter into market and no bad news and also stock market are stable then it's start of bull market. Firsts you will see BTC price will go up and then little correction and then you will see a full bullish trend in Altcoin. For now there is no sign of bullish becauseany negative news in market with high inflation rate and Bitcoin is also struggling.
I also noticed a correlation between the stock market and the crypto market. Yesterday, the stock market had a bad day all in the red, and cryptocurrencies also plummeted. Without any good news coming out, a lot of negative news surrounding the war between Russia and Ukraine affects the global economy. So we shouldn't expect too much from a green market right now.
