I think for altcoin, not as simple like bitcoin which people already know and believe. I mean, for altcoin it depends on their developer, and progress, and maybe any other factors for the coin to be dumped and pumped. Maybe simple thing that we can take about it is, be prepared because if we not prepared when holding altcoin and then price dumped a lot more than bitcoin, it can cause us panic and maybe cut lose our assets.

To be honest, i am one of it. Still not joined market when price dumped but FOMO when price already bounced back. That is why in trading, not only theory which can help like "buy low sell high" but control our emotion, so we are not panic and can do trading clearly, i mean in mind.

I can't create games or not developer of anything. But i think we can't expect more because what they aim is profit for themself, i mean good P2E games both from gameplay and profit usually only in early time. But the next we can count which one is good or not because usually developer only follow what still be hype. Maybe if look for good gameplay, better to play usual games and not P2E.

It is human nature, of course when market crashing people afraid because actually they don't know where price will stop to dumped. But it is funny, i think only happened in my circle too. When price pumped, some people in my group said that they are late, or maybe they should buy some more before pump happen, but when it is dumped, they said that it is time to take a rest from market which actually they could buy some in that moment.

People keep said about fee, but ETH itself have feature which maybe attract their investor like more coin to mining or maybe when in POS, ETH can made people start to buy it and make demands. (to be honest i am not really know when is POS, or maybe POS already started because not follow ETH progress) but my amateur opinion says that it can create demands for ETH.

Overcome or vanquish maybe still need longer time, since ETH still be top of coins although people start to change to new coins, we can see although BEP20 network already launched for year but ETH still dominate and price still much more than BNB. I am not said that it is impossible to happen, but maybe need longer time than we expected.

My personal opinion, i think it is better to be in reputable site like Binance. Although risk is almost same, we don't own the key because we not hold private keys and in Binance people now must do KYC, put our money in something that we don't know or maybe not much reputation that can cause we lose our money. And they offer to stake our money in there.

No matter what value, i think your elder brother maybe can know there are people who care with his child,and then he can do the same. I mean, in bitcoin we can spend as long it is market minimal order or maybe p2p and buy from other else. So he can follow your dream and you both can made his child happy in future, and the $100 can be more and more in future.

Arbitrage for me is more complicated. We should know what cause it and we should take our decision faster because other people might be see that chance too. Because usually there are any problem from the market itself like deposit or withdrawal maintenance and if we don't know that, we can easily lose our money. In past when Bittrex and Poloniex still trend, especially when Poloniex listed new coin, usually it get pumped a lot and when i can't arbitrage, i will just buy in first market and then sell it in same market because people will start to buy it too and it can make price getting higher.

You are right, that is why sometimes coins which have $10-$30 in value, when in past is really worth to sell, now people don't have any choice beside to hold it, and hold not because price of the coin dumped but not worth the profit because need higher amount of money to pay fees, or maybe from that $10-$30 value of the coins, only give under $10 profit.

Not much than $50 maybe, because when i use ETH as transaction, maybe ETH price not high like nowadays. But now, if joined project that use ETH, i will just hold the coin if fees is really high. So my answer for today and in future maybe not much than $50 i can afford to pay fees. Can be higher if the coin value is much more than the fee and it is worth to spend money for fees.

It is yes will need more capital or we just split capital that we already have although it means we bought less amount than what we want to do before, but in this situation, when market morely like to keep dumped, it is worth to do because to be safe is better.

From what i read price can be dumped more, i think split capital which is previously will we use to buy into 3 parts. Because when price keep down after we bought it, at least we still have money to buy more, and the rest if price really move very much and we can buy more with it. I think it is safer to do than decide 1 price and buy it all with capital that we have because no one can predict where actually bitcoin price will go.

If it keep stable link this and morely like downtrend keep coming in a months, maybe bear market really come. I think it is worth to wait for more time, but if already bought, don't need to panic because only in time price will bounced back. If want to try maybe use spare money to do short and it will be worth to try, but as long we always ready for anything that can be happened.

Still need time maybe to decide Polygon Matic is good or not, but i think it make a nice progress. We can see some projects already use it's blockchain because cheaper fee if compared to ETH. But to  be honest in my mind, if the coin pumped in future, what will be happen to the fees, i mean in value must be increased too.

Some of my friends know when i already sell my coins, then price will be pumped. Sometimes it really happen, only in short time after i sell my coins usually it get pumped, but when i hold, then the coins not moved. Like now i hold some VITC token, it keep stable in and no pumped and i only wait for it to pumped.

Easiest way maybe, seeing how people react about the project. Usually new project is posted in this forum and usually who already in long time of crypto warn others if the project look suspicious. About promising, almost all project looks promising because they can write anything without limit and hide behind disclaimer.

I'm stay with a group of friends. To be honest mostly because i don't have capital to buy premium signal. But i think it is almost same, what they give usually only order, stop loss, etc but all not guarantee that we will always get profit. They will hide with "use money that we afford to lose" if their prediction is wrong and if they right, they will show it to attract new subscribers.

There are many kind of scam that can threat people, not only about coins but many kind of investment that attract people to gain profit in short time. It is possible to avoid it as long before we made research before jumped into it, simple thing maybe seek in this forum and see how people respond about the project but we must know who really criticize it or who only shill it.

$5000 with 1x leverage means need to move a lot before get liquidated, and $100 with 50x leverage means only need little spread of market movement to get liquidated. If i have $5000 maybe i will be more confident to trade because (but this is my personal opinion) leverage trading almost like how much our capital can hold our order, so longer that we can stay in market before liquidated is better.
