Holding is not bad but at least you hold for long term with a proper strategy, not just holding and waiting for moon. For example, 30% of BTC in my portfolio is for long term holding while I trade the rest. I can't just be watching coins on my portfolio go up and down without making profit, since I'm a real time trader. However, I'm not castigating those who just hold for holding sake, we all must not have similar motives. If there are more holders, it's good for the overral market anyway.

Talking about the "security sense" as you mentioned, the major reason why I've been using metamask over time is principally because of this. Connecting to decentralized exchanges without actually using your private keys or keystore directly gives metamask users an edge. However, there are fake metamask extensions and a newbie might not be able to differentiate the fakes from the real one. A friend of mine lost 2 ETH after installing and using a fake metamask app on playstore, it was a sad omen but a lesson. I encourage crypto enthusiasts to use metamask especially for some third party transactions which require access to personal wallets or signing in to DEX. Crossing 1M user milestone sounds interesting, but like you wrote, not all users are active.

Did Libra ever pose a threat to Bitcoin? In my opinion it never did. I've been following up on libra and the updates declined with time, the last update I saw was about numerous hindrances delaying libra's launch. To me, libra should expose more people to crypto and also fast track adoption, looking at the user base in view. However, since it's a stable coin, it doesn't pose any threat to the king (BTC). Looking at the present limitations, the real question now should be ; "will libra ever launch"?

I used to think the Corona virus pandemic will help foster crypto adoption, but unfortunately the overral market cap for crypto saw a notable decline when this COVID19 pandemic led to lockdown in various nations. In the real sense, if bank notes are used less often (and in some places people do not accept bank notes due to the risk of Corona virus), more funds should be channeled to crypto market. Many still prefer online bank transfers in their daily life as an alternative to bank notes, and not crypto. If we crypto enthusiasts keep educating the populace about the benefits of using crypto for daily transactions, it will go a long way.

Basically I keep all my BTC and ETH on blockchain wallet, however I use trust wallet and atomic wallet for multi coins except there is a recommended wallet for a specific coin (usually for staking purpose). I don't know about the claims for coinomi vulnerability issues, it's been a while I used that but I had no issues with it. What I run far away from is new wallets claiming to give reward for storing coins in them. The big question is, how safe are the wallets we think are safe? We just have to be careful always.

Telegram is populated with so many scammers ofcourse, especially those private chatting you to invest in scam crypto projects (mostly HYIP) or fake groups pretending to be real projects especially during token sale. A friend of mine fell into the trap of scammers early this year, he was persuaded to invest in private sale of a scam project. Let's be guided, if it's too good to be true, then it's actually scam.

Browser extensions generally are not bad, but there are so many fakes. For instance, metamask extension has done more good than harm, but obviously when you install the right extension. However, for safety reasons it's good to be extremely sure before installing any browser extension. Added to this, third party keyboards are also a big issue, those developed to steal your crypto will steal your private keys or menomic phrase after copying to clipboard and send to the developer. It's old news to emphasize how essential security is important in crypto space.

Well it's not only the Bitcoin market per say. The stock market is crashing and even more, economies are affected, many things not going right and there is financial crisis. Nobody expected this blow, many people got liquidated on leverage trading, so sad. This dump is epic and will be recorded in history I presume. However, I think before halving all these will subside, I just hope so because if not we might not see any bull run.

Very nice suggestion here, and that is what I did today. I converted everything to USDT at around 7500$ because from the chart, the dump was imminent. I'll buy back when I think it's right, for now I'm still in USDT. I might decide to ride the leveraged tokens for max profit, but not with all my capital, just 10%. Knowing the right time to enter the market after converting to stable coin is important.

Most times greedy people fall for these cheap scams, also ignorance can contribute to this. For instance, before opening any link whatsoever, I ensure it's the legitl url and not just clicking random giveaway links. In the case of the coinbase giveaway scam shown by OP, it won't be so easy for someone new to crypto to easily spot, We just have to be careful. Sometimes I see scam giveaway replies to tweets by popular crypto influencers, and gullible people keep falling for it, example send 0.1ETH to get 1ETH. If it's so good to be true, then obviously it's scam.

To a few people, the crypto market dump is an opportunity to get their favorite coins cheap, in this instance ETH and to many its an avenue to panic dump. Well, I already bought some ETH at 207$ and will buy more when it goes to say 175$. I know some will be saying the drift to POS coming soon is behind ETH dump but it's far from it, the whole market is obviously affected. Let's say a some days before halving, those who accumulated their favorite coins at dips should smile everything being equal.

Crypto and stock markets are down but some altcoins are making very awesome moves against all odds. Two of my positions being LEND and BAND gave me profound joy today, well the massive move for LEND was FA based (Partnership with Tether). Not withstanding, 70% of my funds are still in BTC, risk management is very important especially with this kind of market.

If you actually took time to read through my brief write up, you should notice I mentioned "and other exchanges". Binance was used at the topic as a case study because that's where I principally trade, hence noticed the fast PnD for newly listed coins.

The airdrop is partly the reason but not the major reason. I think holders take the listing news as an opportunity to dump. Worst part is that team members may use that avenue to quickly dump tokens at top price.

Recently there have been a craze and buy rush for any coin new listed on Binance but usually turns to a nightmare for those who FOMO too early. $MBL which was listed today because they won vote for community coin dumped from 59 sats to 30 sats within some minutes. This was the case with LTO too. My little advise to traders, (especially newbie traders) is to analyze properly before diving into buying a newly listed coin on Binance especially and other exchanges with such hype. Even if you must do, use tight SL and moreover there is no point chasing a moving train.

There are a few good projects but not "so many" like you mentioned  to be sincere. Most of these projects have already been abandoned by team members in the real sense after achieving their aim fund-wise, and that's why we don't see development progress for most projects after a while. Well, the good thing is that some projects are really giving hope to crypto enthusiasts, and we expect more genuine projects with dedicated team members to sprout with time, even with more improved blockchain architectures ameliorating the drawbacks of existing projects.

I thought I was a pro in gambling until I lost about 3700$, then I learnt the hard way. Gambling to me shouldn't be among a major source of income, if one must gamble, it should be with proper risk management strategy (do not gamble with much funds even when you think you always win, there is always a doom day in gambling). I think OP already mentioned the major sources of earning in crypto ; mining, trading, holding, bounties and some airdrops. Initially faucets paid but not now, things have changed. Nowadays staking too looks profitable, but not to a great extent and it also depends on the quantity of coins used in staking.

Let me be candid here, If you needed money for very important reasons and your crypto holdings are your last resort, it's not bad selling off. For instance you need money for a major operation or treatment of a life threatening health issue, and it means selling your crypto holdings to remedy the situation, it's human to sell unless you are deceiving yourself. If it's a minor issue that doesn't warrant you to sell off your holdings, then there is no point selling off everything. Holding is good yes, but wisely.
