Whenever people sell huge amount of coins/ tokens, price will be dumped, whoever sell those coins/ tokens. No one can control such dumps.
Projects are unable to grow if they can not release good products, good use cases.

In fact, bitcoin fall is a good news and good support for altcoins. It means there are good days for altcoin investors, while there are bad days for bitcoin investors. They are different investors, whom invest in opposite assets, and they do have different, opposite feelings within same period, in the same market.

Dogecoin will go to the moon when it goes, and does not need influencers like John McAfee or others to believe in Dogecoin. It will goes when it consolidates enough to have good momentum. When it starts rising, there is no influencers can stop it, because Dogecoin usually has big momentum for its ride.

I agreed that Dogecoin is a high inflationary coin, that somehow explains why Dogecoin has low price in BTC. However, it has real use cases, and has been widely accepted on so many platforms; that contributed to build up good popularity and very huge communities globally. Dogecoin, in reality, will be able to rise two- or three-fold from its today price. No one when it will rise like this, but it will do rise dramatically (two- or three-fold).

More chances, more risks. I meant with altcoins or tokens, you should accept higher risks before invest. For bitcoin, you won't get loss if you own your  bitcoin for years. I believe bitcoin will keep increasing in value. Altcoins and tokens (bad ones) might tail off over time, very constrasting compared to bitcoin.

3 years ago, lots of issues occur with Poloniex, not only with Ripple. The site crashed for so many times, and each time they openned their site, margin crashes killed lots of marginal traders. I remembered those days, and that was one of reasons why Poloniex shut down its troll box.

I don't want to call it as bitcoin's weaking phase, because it is unavoidable correction, I believe. How far bitcoin has moved from its bottom before it hit $14,000 weeks ago? Too far from its bottom, right? Moreover, you should not forget what the news and drama on Tether USD. I think that news early disclosed bitcoin corrections, and how deeply it will be corrected. 

In reality, altcoins have all moved up, but they at least have still stood at their bottom range. It means that there are still opportunities for you all to take them back. Even if you sold your altcoins more than three days ago at lower prices than their prices today, you can determinantly buy them back because they will jump into altcoin season, a long period of bull run to come.

Bitcoin domination has fallen, that somehow help altcoins to move upwards recent days. It is hard to predict exactly where bitcoin will drop to and halt its falls, but I guess that bitcoin might have its serious correction this time, and might retest its support around $8000. Let's see how its correction occur next two weeks. Today, bitcoin domination fell to 64.5%.

Temtum, in reality, has achieved big success just weeks after its start. Nevertheless, I agreed with you (and I believe lots of others agreed too), that Temtum has more potential to grow. Positive feelings come back to crypto investors, and when bull run starts, Temtum can take advantage of it.

From now on, altcoins will increase gradually, till the end of this month, or till the end of the first two weeks of next month (August). From that, I believe that altcoins will officially start their bull run, the second bull run for altcoins in 2019. Altcoins have nearly come to their endings of bearish period. If you noticed, their volume all increased considerably recent weeks.

My Wallet repeatedly crashes, after each time I open it. I am not sure why my wallet crashes, but it just occur a few hours ago. Previous days, there was all smoothly operations. What's the reasons and how to fix that crash? Are they come from my devices?

Bitcoin will have to be corrected, it is unavoidable if we look at the price chart of bitcoin, we will easily see how far it have moved from its bottom. From its bottom, during its ride over more than 7 months, there is no serious correction, so now it's time, I believe. I still don't think bitcoin will go into its next bullish period in fourth quarter this year. It might be only jump into new bullish wave in early months of 2020.

Yeah, Litecoin rose from around 0.005 BTC to nearly 0.019 BTC. Now, let's take an overview on current crypto market.
I believe bitcoin will turn into its another bullish period, just in very late days of 2019, and might really take off in early months of 2020, when halving time comes closer. For now, I think bitcoin will have to jump into its bearish period, with very serious correction. That will also give altcoins, includes our beloved Litecoin, chances to rally.

All of these in plan of Justin Sun. He made news about a lunch with Warren Buffet, to boost the price of TRON. Then, he gave reasons to cancel or at least delay it to dump the price of TRON. Took profits already (weeks ago), now it comes to time and price to buy TRON back. After all, what's next with Sun and TRON?

Whales, with their huge funds and huge amount of coins, have to move very slowly and silently. So, they can not dump all their coins at once without serious impacts on price. They have to do it gradually, and it is an art of whales. They usually sell their coins over time, weeks with some bumps along the road in order to keep price as high as possible for them to sell and get as much funds as possible.

It is same as investors should not judge a project after reading Whitepapers, because a good Whitepaper is a good component of good project, but it does not guarented that project will be developed well over time, and it will be grow as planned in Whitepaper. There are lots of uncontrollable, and unexpected things in real life.

It is imposssible to conclude when altcoins will rise, but I agree that it is not the time to sell altcoins that nearly hit their bottoms. It is not time to be panic and sell at whatever price just to get Bitcoin or USDT back. It's time to determinantly hold all your good altcoins, and wait till their bull runs to sell at as most beneficial prices as possible.

Yobit does not have supports for their users, not slow-supports. I think there is no support from Yobit to their users. However, it is likely incorrect to judge Yobit is a scam exchange. They are a shady, no-support exchange, but has not still been enough to call them as scam one.

Dump means selling huge amount of coins at the same time. If someone want to sell coins without dumping price, s(he) should do it gradually, by selling small amought of coins gradually. Small amount means small enough to not dumping price. So, time is key too. Selling slowly, hours, or  maybe days to avoid dumping price and create panic.
