Expecting a down trend short term

After a long climb, I expect a trend reversal a significant decline

Perhaps we will once again set a higher top sub 20K, after which I expect a significant decrease 20 to 30%

Comment:

When the trend reverses in a downward pattern
then it might be time to trade altcoins.
If we look at the past I expect a significant increase in altcoins in USD as well as in BTC pairs after the correction of BTC
