You should not be scared of hackers because if you know how to keep your wallet safe no one will hacked your BTC. Like me I used myetherwallet and I only used metamask so it will not be hacked by the hackers out there.

The common challenges of the BTC that I know is the price then the adoption in one country. Then if BTC will be legalized it will be used to pay online transactions.  

It is normal for us to have fear because some of the people have positive and begative issue on the BTC. It is too risky to invest to BTC so for me if you have fear in BTC it is normal because we cannot remove it from our mind the fear of thinking in BTC. Some have fear because it is too risky, we cannot see it because it is a digital money. Someone can hacked our BTC and many more.

Yes investing in bitcoin is not true, because in investing in bitcoin you should know the basic first because if you do not know the basics you will not earn big.

The basics that you have to know first in investing.

All of what I listed is the things that you should know abd study to earn big to crypto and not to loose some of your coins. It is not that easy to invest in crypto if you do not know the things that I have listed you will not earn that big. And you will just end up with regrets.

For me it is the eth who have the potential to grow like BTC. Because in the coinmarket cap it is the 2nd coin that has a good value and the most common coin that is used by many people.

It is good to hodl coins because you will earn big in hodling your coins and it is part of having a crypto is to hodl it for a long-term to earn big. If you do not hodl it for a long-term you will not earn big. If 2yrs is your plan that is good maybe the price if the crypto in 2yrs is good and it is high value .

What I like in cryptocurrency is that I can invest even if I not buy I just need to invest my time and effort in doing some bounties to earn money. I can also buy crypto in low value and hodl it to wait for the value to get high. You can also control your crypto in buying thing that you don't need because if you have cash or credit card you used it to buy and buy so many things that you do not need or you just be in the trend or fashion.

If the BTC decreased you have to hodl you coin and wIt for the price to get high it is good to buy at alow price then hoddl it for a high price if you sell, trade or encash it right away you will just earn small. Right now tge price of thr BTC is good it is increasing for me it is good ro buy now until the price is in 8k but if it reaches to 9k you can sell it but for me you hodl it first to make the price higher. 

Reward for holding is you can earn big or the price if the coin is good becauseif you buy your coins at a lower value then wait for thevalue to get high you will earn 5x the price you bought the coins. As of now the price of the BTC is good but I'm still waiting for the orice to get high so that I will have a bigger value of my coin when I encash it.

You are right you have to read the white paper then you also have to read their roadmap then check their ICO ratings but not all with the highest raring have a good ICO. You have to look if their coin is listed in exchange already so that if their coin is given it can be have a value already because it was listed in the exchange already.

I do not agree to what you have said BTC is not for the poor people thst do not get a job. Because BTC is for people who understand the crypto and the BTC. It is a digital money online, BTC can be an alternative for cash money and for people who doesn't want to use credit card over the online buying. Like me I do not have a credit card and I do not want to use a credit. And in using BTC you can control not like the credit card.

Satoshi Nakamoto is the one who created and designed the crypto but his identification is unknown he never tell his identification to everyone. He is also associated with blockchain technology.  

My advice for crypto beginner is you read some topics here in bitcointalk on how to get crypto for free you can also join some bounties to get some crypto. But you need to learn the basic about crypto. In joining crypto you have to have the patience in doing the buying and selling because if you do not have the patience it is not for you in doing crypto. Because when you buy the crypto in low value you have to wait for the value to rise up if you buy and sell it right away you will not earn big you might loose aome of your crypto.

For me it is trading BTC because in trading you can earn big. But before you earn you should learn how to trade because if you do not have the knowledge in trading you will not earn big you might loose some of your BTC. You should not afraid in doing trading. In mining you have to invest big because you will buy computer parts for mining and if you also don't have yhe knowledge you will also loose some of your BTC in trading and mining you should have understand and know how to do it.

You can find crypto on the forums, you can also join on the telegram. Read some whitepaper and road map and you can also check their ICO ratings.

For me I use BTC because it is the easiest coin to earn it is also the top coin in the coinmarketcal it also has the highest value in crypto.

Altcoin is combination of two alt + coin. alt is a short term for alternative, and oIn signifies the curency. In short it is alternative coins. it is also a group of coins, it is also launched after BTC.

Long term is hodling your coins in a long period of time and short term is hodling your coin in a short period of time it is good to hodl for a long term rather than hodling in short period of time because you will earn big in long term rather than in short term  in long tern you will just hodl your coin and wait for long time for the price to get high in short term if you want to sell you coins right away, you can sell it already no specific price or you do not have a target price to sell it but in lobg term you have a target or goal in selling it.

I choose to buy BTC because the price of the BTC for now is low. It is good to buy BTC if the price is too low and when the price of the BTC gets high it is the right time to sell or trade your BTC. To earn big in BTC you have to learn fist on how to do BTC, but if you don't know how to do BTC you might loose some of your BTC and you sill regret on having BTC again, but I suggest that you havve to learn first the BTC before you enter the world of crypto. It is not enough that you just some one who knows about BTC because not all of us know all the process on how to do BTC. And some will not tell you all what they have learned or what they knew in BTC because it is their lost if they tell you all. Maybe you will learn as much as what they have learn.

I see so ask long as the bounty mentioned that they need to require that your Facebook or Twitter needs to by on that specific bounty like in the signature campaign then you can join multiple bounties is that right?
