I have a few bags of different alts. My hope is that if BTC corrects, the sell off will lead to a buying of alts. Then my alts will pump, I sell them for more BTC, then BTC goes back up. However, I know there are lots of people with this plan, so maybe it wont work. Thoughts?

If someone has a good capacity in trading they will definitely benefit from buying only from resetting and holding, even though earning a small profit will definitely be profitable in their daily trading

You are absolutely right.

market doesnt need any reason to pump or dump.this is a cycle.bitcoin made ath, then a big correction for more than a year and now rising again.it doesnt need anything like sec, big news etc.

Everyone will start to see that others will want to buy more and more as the price keeps rising.
This trend promotes such as new investors and old ones to buy even more and wait for bigger price so they can take out even higher profits.
Those are the main reasons why we are seeing this pump. Also because some known companies have joined the crypto markets.

the rise is natural and doesn't need any reasons whatsoever apart from adoption increasing. this was inevitable too and should have even happened a couple of weeks ago. but now that it is happening all the rest of the positive news such as Bakkt, eBay,... are acting as the contributors to that upward movement and helping it happen more smoothly and at times even faster since less day traders try to sell and go against the market now.

In my opinion then with US trade - China is tense. Chinese investors are trying to drain their money to other assets like USD and Bitcoin, they think the yuan will continue to devalue. President Trump has increased taxes on China in the past 2 weeks, making the yuan 2% lower than the USD. Some people worry that China will reduce the value of Chinese currency to help cheaper Chinese goods to compete with US products despite tariffs. Therefore Hong Kong wealthy merchants are withdrawing money from China

Meanwhile, China is blocking people from selling the yuan and very strictly transferring money from the country, and Bitcoin is the only way. According to calculations by experts, 20% of Bitcoin trading volume comes from China
