Do we need to wait more 1- 2 years then buy alts now before right before bull market kick in?
You don't have to wait 1 or 2 years to reach a good market. You just need to be patient for a while, the market is in correction, and I think it will return to normal in the near future. However, you also need to be careful in trading, this is in order to protect your assets from losses.
maybe one more leg down and we will see bullish trend again, current price drop again and this condition waited by most investors. No matter if wes see bitcoin price crash again , take it as good opportunity for accumulate coins.
