BTC has 2 important supports $17800 and $16800. This will be the target for the end of wave C to finish this correction (analyzed in the previous post).
The updated lower low & lower high topcoins yesterday also dropped to the at the start of this uptrend.
Some topcoin charts are quite bad, you guys should wait for good signals to enter, catching knives is one way but comes with high risk.
After the capitalization of BTC is large enough, the capitalization will pump back to the altcoin, at which point the market will go up. This drop is still only short-term correction.
