Crypto traders have seen a pretty good season in mid-2019. For now, what are the right altcoins to be able to use in trading, in order to gain a good profit (potential profit). Is the right time to choose BSV in the trade basket? I want to hear your opinion. Thank for you all.

I read the news about Ethereum 2.0 will be launched at the beginning of next year (January 2020).
What if buying ethereum for now, is the right time? If there might be good advice from you, let's take time for this.
 Thank you.
