Ethereum is really the safest bet, and it is already proven and tested. But I think the ethereum will still not reach the 5k$ this year maybe next year we can see that eth will reach 5k$, eth drop to 2740$ from the price that almost hit 4k$ it is now 2740$ and we are running out of time on year 2021 few months left and 2022 will start so I think 5k$ will be reach next year.
