If we talking about smartphone can mine bitcoin or crypto coin I think it's impossible or if some people invented it takes few more years or maybe decades because mining if for computer only with high specs , with good ventilation and and temperature is good or below so they did not experienced overheat or anything trouble.

Depends to you how long if you want to hold bitcoin. But you can still hold bitcoin for more years like 2 years when bitcoin become very high. But make sure  you will sell your bitcoin once the price become very high again because for sure once they reach their maximum price they will go down and possible to die.

I don't remember the exact date but I think last 2 years ago when I bought or purchased cryptocurrency and the price on that year is very high and if I know the price increase very high I buy more and for sure im now rich because I earn more money when price increase very high.

I believe 100 percent to this coin but it doesn't mean I will not sell it. Because I believe to ethereum to become very high the price after few years and when the price become high I will sell it and I will not hold it forever because that is purpose of why you buying a coin to not hold forever.

Before i invested to the new release but now I learned enough so every new ICO lunch I do a research and reviewing all information and asking some expert and I follow them but if not good if I think I will ignore this but even is good ICO you need to take a risk also because they have chance to failed and not reach the targer hard cap.

Not all altcoins are worthless or worth zero, because if you go back they have a lot of people are earning a lot of money because of the altcoins and some of them are became rich. Maybe today other people think altcoins is not worth it but for sure they change their mind once they see the price again increasing and many people will earn money again.

Bitcoin is really use to buy altcoins most of the people and investor of bitcoin will buy that coin to buy altcoins because they will earn money by trading altcoins. They have some coins that gives you high profit and you can use your bitcoin to buy or purchase the new coin that you want to get.

That is right crypto will not end, because i believe it will start only because they prefer for the big pump next coming few months or years. Patience is all we need and you will earn more money but if the person is impatient you will cry because you will not wait the price to pump again. Crypto will start to pump if us be united to buy more crypto and no one for sure will say crypto will end and for sure they say longlive cryptocurrency.

The best altcoin after bitcoin is the ethereum because most of the project are using ERC20 and I think they will prefer to become king why the price now decrease because ethereum give us chance to get more ethereum to earn more money after 2 to 3 years from now.

Bounty hunters really cause dumping price of tokens once they listed to the market or exchanges site because they sell their token and only some of them are hold their coin . That is what always happened once the token listed the price become the ICO price so the investor lose some of their capital and only bounty hunters earn money.

No will ripple will not become number 1, because the price is very low and the ethereum is the next king if you may know and many peoplr believe that. But ripple coin is still good coin to invest and we are to buy more ripple and the highest and possible price for me for ripple is hundreds dollars and that is good to make more profit.

If you do not want to hack your account so protect it install a lot of safety features like what Im doing and Im pretty much sure that my walley is very safe from any hacker in online. Remember the safety of your money is depends on how you know the safety for your wallet.

This month is October and we will see if the ethereum really reach 2500 dollars before end of December 2018. Buy more ethereum now and you will earn more profit. I believe the highest possible of the ether is to become 5000 dollars and I think maybe it will not happen or it will happen.

Yes ethereum have big chances to break their highest price before but maybe need more weeks or months before they do that again. But if most people buy more ethereum as soon as possible they will up again and we can earn more money. The good news is will not end because ethereum will increase very high.

This is the right time to wake up everyone and to buy more bitcoin again don't waste more time because bitcoin is ready to pump and bitcoin only need is push from the people who invest more to up again the value. Everyone will benefits on this so buy more bitcoin.

You can invest your 4000 dollars to ripple , waves  and litecoin and that is very good example that become 10 times after end of this year 2018m you can do a research also so you can know what is the coin who become more than 10 times the currently price for today.

For now i don't think you will reach your goal that 10 percent per week to bitcoin. But if you do trading like buying more altcoins maybe you will get that percentage but it's not guaranteed because you will see the market still decreasing but you can do longterm holding and more coins now are better to buy.

I do't think tfor this now we willsee bitcoin 50k dollars for this year of end 2018. Because the possible price only of the bitcoin is 20k dollars in the 2018. Maybe we can move our prediction that bitcoin become 50k dollars in the year of 2019. But it is good if they reach this year to earn more profit.

It's hard to predict if the price decrease or increase. But most we hope is to see market turn to green but not only hope or predict is needed. Market need a buyer again to recover it's from the dumping price. But I believe after few months high chance to recover the market.

If the bitcoin price increase they have some effect also to the altcoins maybe not big but atleast increase a little. Like this situation price of the bitcoin decrease and most of the altcoins decreased too. Maybe they have connected to each other but it is only a little .
