Altcoins that have good fundamentals definitely have high trading volume. This is my choice to minimize risk, because Altcoins that have low volume and low market cap are quite easy to manipulate. The Top Altcoins in CMC are the best choice for trading or investing, because prices are quite stable and have good fundamentals.

escrow is the best option, and distributions of vesting 1 - 3 months, like the bounty managed by bubbalex. because what I know, the Bounty Hunter after receiving the coins/tokens will definitely be dumped. but BM, escrow, that's all no guarantee, the main point here is the project, I think a successful project will keep its promise to hunters. It is useless to receive tokens/coins but they are of no value. 

Before paying attention to the 10 guidelines that the OP calls, I first look at the Innovation of the project, use cases, products, and how important the project is in the future. Scam projects can be identified with fake teams, plagiarism whitepapers, or content that copied previous projects. Scammers usually promote their projects by promising multiple returns on investment or does not make sense. and only gullible people become victims.

Everyone's trading or investment management is different, and tends to have their own strategies. It's not as easy as you say, to do that requires careful analysis and research. By buying and selling when the price is 2x, I think it's a good option to minimize risk. because sometimes our emotions are formed for greed which makes losing trades. But for an investor it is not suitable, because the project is promising for the long term, the return on investment will be many times and the profit is maximized.

Yep, currently the Polkadot advertisement is to replace ETH's position, with the aim of attracting more investors. If ETH 2.0 fails it is highly likely that Polkadot will replace it, because Polkadot has taken it one step further. the Polkadot project is very ambitious, has evidence of real use cases, and a broad community. Of course I did not waste this opportunity.

Is it time to invest in Polkadot?

Yes for investors, but no for traders. Currently almost all alt has been dumped by investors/traders and focus or switch to BTC. Before you miss the train, DOT is very suitable to put in a bag. I believe in Polkadot (DOT), this project is very ambitious. Many people say that DOT will put ETH position sometime in the future, because basically ETH 2.0 is too much delay and can be said to be too late. this is just my opinion. But until now it remains "ETH The King Alt".

I want to know how to prove real use cases. DLRS? i think it looks like a previous token Yobit made. Many exchanges other than Yobit provide incentives to communities that are much larger and have a better reputation. Just ignore it, don't be supported, it's just bullshit.

The last time with Yobit was sigcamp last year, and is currently no longer with him after learning of the rottenness of the Yobit exchange. :p

That is commonplace on the Binance exchange. Any coins / tokens new listed on the Binance exchange will be pumped 2x - 15x, specifically the launchpad, the new launchpool. this is HYPE and surely the price will go down, until the trader or investor declares the price accordingly.

Maybe OP has had AUDIO in the past or is currently already take a profit. 

quite difficult to find airdrops that really pay, some are legit but (1: 1000). like looking for a needle in a haystack. Sometimes legit airdrops are attacked by people, while allocations are small and only get a few cents. So airdrops are just a waste of time. My advice is to avoid airdrops that ask for personal data information and use a different gmail or social media account specifically for doing airdrop tasks.

Maybe Polkadot, but there is someone who says DOT is HYPE and the pump is too big. But I believe Polkadot can replace Ethereum's position, especially if it fails in 2.0 later. So far "Ethereum The king alt", it's really hard to beat, but there is still some hope for a potential Top coin. and if ETH 2.0 is a success, there is no hope for the other coins to beat. 

It looks like the DeFi trend is still going on until 2021. But I have more hope for the coming year Massive adoption of crypto. scammers always take the opportunity TREND / HYPE, so be careful to invest, DeFi is currently almost the same as ICO 2017, the difference is that investors are now wiser in choosing projects. I hope there will be more new innovations in the coming year, because I'm getting bored with DeFi.

It's hard to believe in a project like this, how can he prove it is safe? while Bot requires private key access. I am willing to trade on uniswap not sleep for 24 hours, rather than using Bot but risk losing all my assets. I don't think anyone will use the Bot service if it can't prove it's completely safe.

Bounty campaigns, sigcamp, social media, blogs, and others. this is a form of promotion and marketing strategy of a project. I don't think the signature campaign really matters to increase the credibility of the ICO, because basically investors see the use case and how important the project will be in the future. Investors can not only see from the bounty, it needs serious research and analysis. But with the bounty, the project will be widely reached and targeted, namely crypto enthusiasts.

I also struggle and sometimes the fastest option in metamask doesn't match the estimated time I think. I often add GWEI manually, based on the fastest GAS price. I often lose, especially the bonding curve that causes "GAS WAR". Hope the metamask has a significant update.

I don't know since when that term appeared. But the point as an Airdrop / Bounty hunter is how to get coins / tokens for free and the risk is just a waste of time. the difference is, Airdrop only carries out one task and waits for distribution, while Bounty requires daily consistency with the rules or conditions until it's finished and waiting for distribution.

it's optional in my opinion and as needed. My advice is not to store stablecoins for too long. USDT is more popular than DAI, but USDT has many cases of freeze. But for ICO / crowdfunding, a project mostly uses the USDT option for funding. You can choose according to your needs at your own risk.

SKALE, I knew from the start that this project had great potential in this year and next year 2021. I only had a few SKLs, because the purchase of tokens at that time was limited to around $1000 per person. The sale of the SKL token is very fair, as the price is set at $0.03/SKL. SKL parnership with 25 leading validators such as ANKR, Dokia capital, etc. Currently the token is locked until November and December to be launched so that the economy runs.

With this news, crypto shows that it is indeed for the future and Paypal indirectly popularizes crypto for the world. I hope 2021 will be the year of massive adoption of crypto. The 4 coins that Paypal mentioned jumped in price in 24 hours.

Last week I'm buy some Ethereum, and this news was shocking. I took a lot of profit in just a week.

TRON in my opinion this coin with the lowest fees, and I often use it, especially withdrawing USDT on the TRON network with 0% fee (withdrawal from the market) if on the network with only 1 TRX / $ 0.02 you can send TRX / token. I chose the TRON option because it was fast enough to confirm on the network. LTC fee is also cheap but it is a bit long waiting for confirmation on the network and this is only a coin like bitcoin, no token. But lately I often use BSC BEP20 (Binance smart chain) for trading on DEX, providing liquidity, farming, etc .. I switched to BSC because network costs are very cheap when compared to ERC20.

The risk of being a bounty hunter is a waste of energy and a waste of time. Before promoting a project you must be thorough and do research on the project. $20 is still better, many bounties don't even pay off. I think complaining is useless, because this is indeed a risk of becoming a bounty hunter. and I hope don't make Bounty your main job and you must have another source of income, such as trading / investing, etc..
