In my opinion, bitcoin is going to the end of downtrend.
- Bitcoin need to re-test 5k5 to have a good pump.
- Around October, bitcoin could exit the downtrend and starting uptrend. It could achieve 10k-12k6.
- For altcoins, we can consider to buy from now. They will  escape the downtrend before bitcoin.
Do not sell anything at current situation. If you can do trading, it's good. If not, just hold and wait 2 months. Good luck!
