ETH price has been fluctuating in recent weeks as there will be news about ETH V2, the perfect time to do day trading especially Margin Trading, because if Spot Trading the profit is not too big, and it will take a lot of time to get $20 to $50 in a day.

As far as I know there is no way to cancel the transaction if you have pressed the send button,
if you use Trust Wallet, the transaction fee should be automatically calculated by the system so that congestion will not occur,
if you change the settings my advice is to switch to automatic mode, or reinstall the Trust Wallet application.

I'm not following the YouCash bounty, but if the allocation is only 2% then the price shouldn't fall very deep.
but either the investor or everyone is not to blame,
that should be blamed is team that does not buy back, if the project does an ICO, IEO or Presale of course they have the capital for buyback, and this must be done by every project to maintain its value.

For beginner investors, choose coins that have a good market capitalization, don't be easily fooled by the hype that is going on.
most of the hype in cryptocurrency will end up losing, because cryptocurrency is very dependent on market demand, when market demand decreases, the price will fall ,.

Do you have a link to the news? because when I searched the internet, I only found about the Reserve Bank of Australia explores central bank digital currency, and that's just talking about stablecoins not ethereum.
this is the link I mean https://coinrivet.com/reserve-bank-of-australia-explores-central-bank-digital-currency/

Actually distributing all the prizes directly is not a mistake as long as the team has made preparations and buy back the coins, unfortunately the team did not think about it, so this is not the fault of the bounty hunter,
Gradually distributing is not a bad idea, but it would be dangerous if suddenly the team leaves and the project becomes a scam.

I see the picture above has some clues about numbers,
because usually the background image of a person riding a horse is identical to a forest or tree, but this is just a color,
and each color has a unique code, for example like this.

Tokens or Coins whose price does not recover after the dump are mostly shitcoins, it is better to avoid coins like this,
Bitcoin will remain the best at least until the bullish end to come, because there is a chance bitcoin will Bubble and altcoins will replace bitcoins.

Too many scam projects about DeFi, it should be a lesson not to easily get caught up in DeFi projects,
some analysis to avoid a scam project including looking at the profile and background of the team, try to look for details and make sure directly whether the profile is real or not, because now there are many fraudulent LinkedIn accounts that use other people's identities.

Escrow is an option and it's not mandatory, but bubbalex is one of the best bounty managers on the forum even though I don't really remember having followed a project he managed or not, I saw the projects he worked on were mostly quality,
Bubbalex indeed often limits participants who participate in his campaign and that's good, because if there are too many the prizes will be less, this is where the role of the bounty manager must be wise when making decisions.

To this day I am not interested in investing in the DeFi project, because from the start I saw DeFi has a big risk, it's just that many people do not understand the scheme,
I think ICO or DeFi have the same big risks even though in several different aspects, but somehow it is risky and as investors it's better to focus on minimizing risk rather than profit, this is an important point.

Depending on whether I want to save it or sell it again, if I want to save it I prefer an altcoin pair because withdrawal fee is cheap when I move to my personal wallet,
but if it is for sale again I will choose bitcoin pair especially when BTC Dominance is high, the value will increase faster.

I'm not sure how everyone will respond to this thread, because there is a lot of news about Polkadot and there is even an investor who gave a $20 million fund,
Polkadot has great potential like the DeFi Project in general because now DeFi is the newest cryptocurrency trend.
My advice for investors with limited funds who want to invest in Polkadot, invest at least 10% of the funds you have, the rest you can use for major coins like Ethereum which is clear and has high liquidity.

I prefer DeFi coins which have big market cap like Chainlink, Uniswap, Maker DAO, etc,
market capitalization is very important to keep prices stable,

Today's airdrop is not profitable at all, fraudulent schemes have been around since the ICO trend in 2018,
it's better not to follow the airdrop at all, especially airdrops that require KYC, even if the airdrop pays are you sure the value is in accordance with your personal data?
whatever the reason today, airdrops are no longer profitable,
exceptions for airdrops on well-known platforms and not needing KYC can be followed, because it guarantees big profits like UNISWAP.

Not all altcoins can be hit and run, some altcoins can continue to be held because they have strong fundamentals, Litecoin and Ethereum are one of them,
If a coin like NXT or Waves, even though it is an old coin I do not recommend it because the development is not good enough  (my opinion).

How can you be sure if his asset price will go up and his capital will return?
He has held for over a year and there is no progress,
I would rather sell at a loss and buy other coins that have good potential, or if he has a lot of capital buying more coins without selling them is the right choice.

Yes, this is one of the weaknesses of coin staking, the value of coins will continue to decrease if there is no market demand, if you really like coin staking it is better to choose coins that are active and each month has a clear development,
because if there is no clear development it is likely that the coin price will continue to fall.

It would be better if you keep BNB on the exchange, you don't have to worry if Binance suddenly gets a hacker attack, because CZ will be responsible and compensate for all losses, this is Binance's advantage,
Besides, if you save BNB on the Binance exchange you will get a lot of benefits, such as trading discounts and passive income.

my advice for beginners is better not to choose fluctuating coins, volatile coins usually have little liquidity so they have a very large risk,
It's better if you choose a major coin like Ethereum or Litecoin, although it requires a lot of patience, but the risk of loss is very small.
