Right now both of them are not good for investments. Personally I expect that the market falling will continue until Bitcoin crash under 2K$. I think after SEC decision about ETF in the end of September it will hardly crash and we will see bottom of this downtrend only in the end of spring of the next year. By that time Ethereum will crash under 70$. According to my knowledges in technical analysis I think that this downtrend will last till the middle of the next year. Only after that the market recovery slowly will start. I expect that fully recovery takes about 1 year and we will see new ATH of the market only in 2020. That's why now it is better to stay away from the market or open short positions if you have enough experience on it.
