You already know that the best coin to invest in is bitcoin, then ethereum as a second choice, but if you prefer to invest in other altcoins then there are several altcoins that you can choose, especially the altcoins in the top 10 marketcap.
And if you want to invest in a new ICO project then you can consider the project that is in your signature, JACS, even though their income is not good but they still pay their bounty participants, and I think this is a good sign of JACS.

As a safe alternative it is true as you say, we only need to invest in well-developed altcoins or top 10 altcoins.
However, even though investing in ICOs is very high risk, especially many ICOs are scams lately but if you can get a good and successful ICO ahead of the increase in bitcoin prices like now then the benefits you can get are much greater.

There is no way to safely invest in an ICO, because we are going to invest in a project that doesn't exist at all, we are only given information about who they are and what their strengths are without any legal consequences they will get if they cheat us.
I myself have never invested in an ICO or a new project, not because I didn't want to but I wasn't prepared to lose my money or I can't bear the risk.

How do you mean that other coins are better but the king of coins is still bitcoin? So that better coin can't be king? what a humble coin lol
If you think there will be other coins that are better than bitcoin then you are saying the emergence and development of bitcoin is just a hype.

In the past, many airdrops were legit and paid, but now it's probably only 1 in 100, of course, don't ever hope that we can get something wort it from airdrop now adays.
You don't really need to pay attention to airdrops with criteria as you mentioned, because in the past most legit airdrops also didn't ask participants to send eth on the grounds of fees, if you want to join an airdrop then just join airdrop with a simple task.

Times like now are the right times to get in, but you must be ready to invest in cryptocurrency that sometimes we need time to be able to get profit, I would rather invest in bitcoin or ethereum now than invest in an ICO or new project.

Honestly, I didn't expect the price of bitcoin to fall this deep, is it still reasonable if it's just a price correction? because previously I thought bitcoin would not drop below $ 18k, But now it looks like it's going to go deeper.
Altcoins are also of course affected by the decline in bitcoin prices.

Only a month left, it looks like it will be difficult to reach the new ATH for both bitcoin and altcoins. But yes who knows for sure, anything can happen in a short time in cryptocurrency.
Some people who are experts in cryptocurrency that I know have never said that bitcoin is going to the moon this year, they just said it would happen in 2021, but if only to reach the new ATH there must be a chance.

For me bitcoin is still the first choice, but if you have to choose altcoins then ethereum is the best choice for now. You can't resist the current ethereum hype and we should take the opportunity to take advantage of this situation, $500 is a small price when compared to the developments they are currently doing.

Some people have predicted that this will happen, some corrections will occur in the price of bitcoin and it turns out that altcoins will also follow and this isn't something we need to worry about.
Now it's time for us to decide when we will come back in.

I have some friends in the fb group who have also sold their mining rigs but they did it about a month ago, I'm not sure if they also sell their mining rigs for the same reasons as you do, but what is clear is that they do it because the results of mining are no longer relevant. Hopefully they won't keep their money too long and pick the right choice as you did.

The point is don't make decisions just because of what you believe without constantly monitoring the price chart. especially don't get carried away by the hype out there, because some peoples will deliberately spread the hype to take advantage from that.
But don't be sorry if it turns out that the bitcoin price is much higher after some corrections ahead

I personally don't really matter the rank of a bounty manager, but the reason I often participate in bounty campaigns from managers as you mentioned is that I find something convincing from the projects they are working on. When a bounty manager like Hhampuzs handles a project we will be curious and want to know what the advantages of the project are so that he wants to handle the project. Automatically we will find out about the project, and if we find something convincing there, then we will participate in their bounty campaign for that reason.

Ethereum is the king of the erc20 tokens, not the king of all altcoins I think, although it is true that currently ethereum is still superior to other altcoins but they are on different paths. And it is not impossible that one day Ethereum's competitors will succeed in beating Ethereum in the market.

It's never too late to invest in bitcoin, you will not lose your money because of it, it's just about how much return you will get on your investment. For now, everyone is sure bitcoin will hit its highest price with prices in excess of $ 20k early next year.

Everything can happen in the crypto world, but to be able to conquer eth is not easy. There have been many altcoins that have been claimed to be better than eth but still they have not been able to conquer eth until now.
The strength of Ethereum that is difficult to compete with is their very large and solid community, and most of them are people who are already experts in the crypto world.

Actually I prefer to invest in gold, maybe this is also because of the traditions in the area I live in because here the benefits we get from gold are not only from the fluctuation of prices. But the current gold price is still very high so it is not suitable to buy gold at this time.
As someone who already knows about cryptocurrency, it would be naive to have capital and not invest it in bitcoin at times like now.

If we want to compare eth and bitcoin prices in 2017 with the current eth and bitcoin prices, the current eth price should have reached $ 800, but as we see, eth price is still far from most people's expectation.
The reason is, the current situation is much different from the situation in 2017 from various sides, especially the supply of eth which is already very large.

Polkadot is still too young to be able to beat ethereum, but for the next few years it seems likely that they can take the throne of altcoins from ethereum.
Because to achieve this goal, Polkadot can not only rely on their sophistication but also the strength of their community, and of course this takes time.

Won't the problems you mentioned end soon when ETH 2.0 is launched successfully? These few months have indeed been the worst for ETH, however, a solution has been established and will immediately address all existing problems.
I actually think ETH will come back stronger and will reach their new ATH.
