Bitcoin cash is exploding since a couple of days ago. This is mostly due to the inclusion of Bitcoin customer service desk in Korea/Asia which excites people in Asia. That is a really interesting thing happening now which helps improving the price.
Mining BTC and Bitcoin cash profitability is now similar between BTC and BCH and this is due to automatic difficulty adjustment of mining pools.
I don't believe Bitcoin cash price increase will continue at the rate seen in the past couple of days.
Here are some tips for buying coins these days:
1- If you are planning to buy crypto right now, don't move in at once. Buy every week, every month, ... with this strategy, you won't lose a lot of things fall apart
2- For day trading, it seems that Bitcoin is the best crypto for these days. Day trading is quite risky because you never know what will happen tomorrow.
