Yeah i totally agree with your question that most of people are investing their money wrong ico, because they are not researched about them.
 here is one way to identify legit ico if particular ico has forum on bitcointalk.org and it has started campaign than it would be consider as legit ico. People can invest in it.

No never because it can't be profitable at all.
It is totally depend upon the hardware of the particular device. mobile devices are made up for only simple use for mining we need Hardware that is made specifically for mining.

Yes this interesting to see how bitcoin has risen in last two days,
It was dramatic changes in its value, Now a days people are making so much of profits.

now a days bitcoin mining is less profitable because difficulty will increase with increase in price,
buying and holding will be the best option for us, because i see so many people get profit from bitcoin trading.
TBH mining needs  maintenance expenses and electricity expenses also. but in holding we won't have to worry about other expenses instead internet expense.

yes now a days interest in bitcoin is increasing because if its price, people get attracted by its price. people use bitcoin for making profit from trading in bitcoin.
As World govt. took opinion on bitcoin like( indonesian, china, russia) it is also one of the reason people got to know the potential of bitcoins.
It is world highest rate decentralize currency.

Fiat currency can't be crashed, because our country economy only depend upon fiat, bitcoin can't be use for trading purpose like Imports and exports.
and fiat currency has plus point that it would be usable by every one in the country. most of people in the world use fiat currency.

So i think here every one want to be a rich person, we all  have dreams to be successful so but we should need motivation dedication.
When we talk about richness that means we are talking about money, where the money come from, it is not just miracle happen.
we have to earn with strategically whether trading, lottery or long term investment.

I think Indonesian ban did not that affect on bitcoin as Chinese ban did, I think Indonesian Govt. did not take bitcoin as an opportunity.
BTW Indonesian currency is one the down currency in the world, I think this is only reason to ban the Bitcoins.

Yes suppose bitcoin has stable price 6000 USD, it has obvious that bitcoin still popular. But people would not able to trade because there would not have any benifit of trading.
People would only concern about signature campaign and gambling. There would no holding for long term .

Thank you sir payment received.

According to me it is very risky because crypto is decentralized currency, none of country will eliminate fiat because if they do than how the trade can be done with other countries. It maybe possible That other  country not legalize crypto.
                                                            It would be very difficult for country to survive with crypto.

I am using online wallet (blockchain.info)
I have been using blockchain since 2 years, i have not seen any fraud activity.
It is secure than any other online wallet and also support ETH.
Blockchain has tie up with unocoin India and we can directly buy bitcoin from blockchain.info .

Altcoins are very active now days, as we seen ETH, BCH is high. Their prices encourage people to invest.
I am not only talked about Altcoins let's see ICO token also, people invest money in ico token and get profit from it.

Yes bitcoin has potential to reduce unemployment, many people now a days earning money from bitcoins that mean they are not unemployed anymore.
let's see how many campaigns are running right now bitcointalk and how many people are working over there,
People are working in wallet servcies ( blockchain.info),
people are working in exchanges.

So we can say that crypto has made opportunity for people to work ,

Yes if you really want to such big profit from crypto than you should need patience and holding  crypto for long term.
I know few people who got 1000% profit from bitcoin because they had patience and risk taking quality.

Once it has confirmed, I will send tip.

There are many ways to get money from crypto. for example - Trading, Investment for long term, Signature campaign and Gambling etc etc.
Signature campaign is very good method for making money from crypto,(doing posting on daily basis). Gambling doesn't that much profitable as compare to others. but only in signature campaigns risk is negligible but others always involved risk.

Actually we can't force someone to like bitcoins  but whose does not like bitcoin then they will regret one day.
TBH with whom i have talked about bitcoin, They have liked bitcoin and want to earn bitcoins.

Bitcoin for kids is not suitable because it would be distracted kids from their studies.
As we seen kids get attracted easily, so we can't tell them about "How to earn bitcoin",but we can only tell them about bitcoin technology or blockchain technologies. This will help then to gaining some knowledge.

TBH i will preferably Buying and holding bitcoins, because now a days Mining need too much investment needed best hardware with highest Hash rate for eg. Antminer. Mining is also difficult because it needs electricity, proper maintenance of hardware that makes hardware too expensive.

if we compare mining with buying and holding than buying and holding is very easy, just bought and hold and sell when price will high.
but buying and holding is involved risk always.
