ETH is still the safer investment for alts but the safest investment is still in Bitcoin. I believe it will reach 10-20k again come December or January and in fact I just bought some BTC when it was around 6.2k. I should be able to double my investment in the near future. It's just a matter of patience!
Not only ETH was worth to invest they have some coins also that have some potential and worth to invest, Just bitcoin or XRP this two of coins was i know that have some potential to increase the price but it come to long to wait.
