If you have the patience for long term holding, then current low prices are a good chance to buy good coins at cheap prices. It is safer to buy top ranked coins.
Etherdelta got hacked too many times so stopped using it long ago. forkdelta is a good replacement. IDEX is even better but they require KYC now so not a true DEX anymore.
Altcoin season will come once this long bear market is over. The baby bull of first few months of this year was in some selected top coins only so a full blown altseason needs the real bull to be back.
BTC price is holding in the low $7000s and hopefully it is getting ready to break out in the $8000s. BTC will be really bullish only when it can break above $10K and hold above there.
Binance did really well in the 2017 bull market but now there is a lot more competition and too many exchanges so it is not going to be easy going forward.
Altcoins have been in a severe bear market that has destroyed the faith of most investors, particularly the ones who invested in the last two years. But next bull market will be back soon and should be bigger.
The super high opening trading prices of Zcash--it was trading more than bitcoin for a few days--are hard to expect again. However, it should have a good rise in a bullish market.
If bitcoin goes down to such a low in $5000s, it is likely to mark another major bottom and bounce back fast from there. Most top coins will likely move down with bitcoin and bounce back with it.
I think bitcoin and many top coins had a nice bull run for the first half of 2019 and have been correcting that bull run since then. This correction should likely end this month similar to 2018 and then next bull run should start.
There were very big bull runs after the last two bitcoin halvings. There is no reason to expect this time will be any different. Current low prices in bitcoin and altcoins are a great value to buy more.
The market is most likely in final stages of bottoming. Once 2020 begins and bitcoin's May 2020 halving looms closer, market should start its next bull run.
There must be good reasons why Litecoin has stayed in the top ten coins list for a long time. It is a well established project with a nice dev team and big community so will follow bitcoin up in coming years.
Good bounty campaigns have become less frequent due to the almost two year long bear market in crypto. Also, a lot of projects are failing to raise enough money so those bounty campaigns can go unpaid.
Plenty of altcoins have been making new all time lows while BTC and the top ranked coins are at higher lows than their December 2018 major lows. BTC bear market is most likely over but it needs to go above $20K to signal next big bull run.
It is hard to expect prices going so low but many technical analysts do expect a lower low after current bounce is over. That should create the launch base for another multi-month rise.
Most alts that show up with high % daily gains are very low marketcap coins that can pump big with small amount of buying and dump equally fast when traders take quick profits. It is best to just avoid these.
