There is no confirmed date when start bull market but definitely we can understand of this year last month. You can see btc price not move on yet so btc price without no expected altcoins green market. I have no tensions because i am a little invest but bull market urgently indeed for billionr investors. Anyway altcoin rising possible but after rising btc price.
There wouldn't be an actual confirmed date. Anyone who can pin point the exact date is just bluffing since everything here is just speculative. We can predict the range of the possible bull market time with the help of technical and fundamental analysis but I believe no one really pin point the date of the start of a bull market. There are signs that the bull market will arrive like forming new trends and arrival of big investors that will certainly hype people. Altcoin prices will just rise as bitcoin rises unless we can see an opposite effect this upcoming bull market, No one really knows.
