All of these coins may still be here, but I don't think all of them will stay in the top 10 for many years.
Of the ones you mention, I would say Litecoin and Bitcoin will hold good positions, as they are the only ones on your list that have solid tech.
Also, not much to say about Decred, since some aspects of this I still need to understand.

Almost thirty percent drop in the last seven days... Nothing new for altcoins, but for a multibillion dollar market cap it's a lot.

If devs and miners manage to finish the year with Bitcoin+SegWit in a single chain, I think that is possible.

Not many, since I do not live surrounded by many tech people.

Try to have a good timing when using it. In the past I have had success using it in the first minutes of every hour.

Really sad that this happened, I know very reputable people in crypto who fell into this scheme.

Good to see this happening. I do not think the activation will take the currency to fifty dollars or something, but the important thing is the benefits this will bring to the ecosystem, and to Bitcoin, of course.

I learned the hard lesson of not putting all the eggs in the same basket. Since then, I've saved something around twenty percent of my portfolio in Bitcoin.

Lately I've spent most of the time in crypto, but when that does not happen, I usually visit games related and hardware related youtube channels.

Among the thousands of banks around the world, certainly some of them already provide this possibility, but the point is that this kills the purpose of the coin.
In addition to relying on third parties to gain access to your coins, you would have to pay much higher fees compared to normal use of the currency.

Interesting... before it became official, I suspected the pump had some relation to segwit. It will be interesting to see where this goes, and speculate on the effects of this if the improvement comes to Bitcoin.
