i guess BCH can go up to 0.20BTC again what do u think ?
No chance. Look at the graph of BCH against BTC. The ratio has been in a slow bleed out for months. They peaked at 0.2, they are now down around 0.06-0.07.
BCH doesn't know what it is. They are potentially forking again to Bitcoin ABC or Bitcoin SV or some other nonsense. The entire thing is a scam. If I were you I would stick to BTC, but if you have to to pick BCH or ETH then definitely ETH.
Thank you for sharing, I also always trust ETH will return to level 1k $, I keep some ETH at the end of the year except when it ~ 1k $ and now only 1/4 of the price then!
