So I have been out of the loop from cryptocurrencies for a bit now and wanted just a brief introduction about potential altcoins to look at? Thank you! 
You may want to check on top 20 altcoins. Altcoins have been doing fairly well, we saw significant changes this year especially. Altcoins endured a lot of turbulence and created a trust zone for themselves. We must embrace the potentials as they may come up to BTC's potential in years ahead.
