Invest in the ICO when the bear market has an advantage, namely the market is still sluggish so prices are low and investors must look at and analyze the platform offered because coins that will be traded on the crypto market must attract new investors so that prices can rise.If prices stagnate because of the bear market, of course they have to wait until the situation is conducive to trading and turn into a bullish market.
