Mining is costly because of expensive hardware,mining rigs also electricity price mining is not possible for everyone but who can get these hardware with cheap price,low cost electricity and proper market research then mining is possible. if peoples think they can't mine bitcoins so how market get supply and how fulfill demands of buyers.

Supply and demand is responsible for rise bitcoin price because many investors are getting interested and buying bitcoins in more quantities so less of supply of bitcoin is possible also many countries is trying to regulate bitcoins,this is the possible reasons of bitcoin price hike.

yes this can be possible in future because more and more investors is increasing day by day and in future bitcoin demand will be more so shortage of supply is possible and in future bitcoin price will fly like rocket and who are buying and holding bitcoin these days they will be in good profit but this is the matter of time but this condition can be happen in future.

hardware wallet and paper wallet is best for long term bitcoin because hardware wallet is not connected with internet and u can access this wallet from private keys. coinbase is a good wallet also this is a old wallet and reliable but i am not suggest u hold long term in this wallet,if u want to do trading with exchanges then u can store Ur coin in exchange like biittrex, poloniex, binance for security u need to create 2FA security.

Bitcoin opening new faces for economy because this is a digital currency and many government are planing for regulate bitcoins also many investors are interested for this currency because of price hike in December 2017 also many websites are accepting bitcoins for goods and services & in many countries bitcoin ATM is running for digital transactions.

There is no collateral for bitcoin because bitcoin is a decentralized and volatile and investors purchase bitcoins and hold till price not move upward and take profit. for bitcoin movement need demand and supply and whenever this happen then bitcoin will be exist in the crypto market.

I think yes in 2018 crypto will be in mainstream because from last six months market was dead but in July market is moving also people are adopting crypto fast and taking interest of investment in crypto markets also in 2018 we can see many changes in crypto market how business markets and merchants accepts payments in cryptocurrencies and this steps give crazy moves to crypto market.

Bitcoin regulation is necessary for peoples and markets so they can start adaption of bitcoins, but bitcoin is not risky for environment because experienced person know how to manage, bitcoins is a  volatile and decentralized currency also its price is depends on blockchain network,demands & supply. lose is depend where we invest or put our bitcoins.

Bitcoin ATMs not work like regular ATMs which giving money cash in hand so Bitcoin ATMs transaction will be digital and bitcoin exchanges and wallets takes time for transferring bitcoins whenever transaction not get confirmation on blockchain, if peoples wanna send bitcoins and money then they can send bitcoin or equal money of their bitcoins from bitcoin ATMs.

Bitcoin price is moving and this is the biggest slap on face who is talking bitcoin will die, they are giving wrong info and make investors panic.
but they don't know what bitcoin history telling us whenever was market went down then definitely in few times recover and we saw a bullish mode
so majority of investors exist in world who wanna invest in bitcoin and supply and demand going perfectly so this currency never die.

yes this is the biggest threat for jobs because including me and many peoples doing full time trading with bitcoins and don't doing job but its not threat for national currencies because peoples are still using fiat currencies in their countries, for bitcoin as a major currency for world wide take times for adapt so we can say bitcoin existence can disturb jobs but not for national currencies.

Bill gates is always against bitcoin because he support share and  stock market and he think if bitcoin attract investors so no one will buy his shares and he can't manipulate his profit so these kind of rich persons is against but in my opinion bitcoin is a best currency and this can change our future and economical condition.

Yes i am holding but setting stop loss on exchanges with market movements also who sold their bitcoin with low price they are now disappointed and they thinking why i sold many experience holder is Still playing with bitcoin market movements and getting profits one thing always remember right time of hold and sell both are beneficial for smart crypto investors.

For bitcoin become world first currency need to wait for government and market adaption because this kind of things take times if we are talking about bitcoin then now many investors are interesting in this currency and slowly all will be adapt it also its transaction fee is low so we can send this currency world wide with small fee.

I hope this is possible in upcoming days hospitals accept payments as a bitcoins from patients who is taking treatment from hospitals, also we can buy our medicines and hospitals give Doctors, nurses and other staffs salary in bitcoins, if peoples getting treatment from hospitals using payment method of bitcoin then this will be beneficial for economy and cryptocurrency future.

yes definitely here is two teams supporter and haters of bitcoins and if we talk about altcoins most of peoples buying coins from ICO because they think its cheap and we can make huge profits but many ICO is scams and they loose money so better concentrate on bitcoins and we can do short term trade or long term holds and make profits also if we wanna buy altcoins then choose strong coins first see their development team and their history then invest.

Hold and sell both are complicated words in cryptocurrency terminology because its quite confusing when we need to sell and when hold, many peoples hold coins when their price is up and then they not sell and other peoples start selling coins when market is down because they get panic for loss, from few months we are seeing everyone is using words hold coins but we need to understand when sell a coin and when hold because this is the matter of time.

Invest into bitcoin because bank never give u good return of Ur investment but bitcoin give u in future if u are planing for long term hold then go for bitcoin. because in upcoming time bitcoin price cross his last ATH and if Ur uncle are not giving u permission then saw them statistics of bitcoin price growth from 2010-11 then convince him to invest in bitcoin.

yes bitcoin has really comeback because in last few months we are seeing bitcoin price was less then 6000$ and now is 7400$ and this the the good news for bitcoin holders but now bad things is all other altcoins are in bearish mode whenever bullish mode of altcoins will continuous then bitcoin will be strong, hope now bitcoin cross ATH price.

Always this kind of situation happen when bitcoin price is down because panic creator create panic and that time who hold bitcoins get panic and sell their bitcoins because whales and panic creator wanna buy bitcoins who keep patience and hold bitcoins then they get good return, bitcoin never let down us when market in bullish mode then they shut their mouth and disappear. i think now bitcoin strongly going up with continuous bullish mode.
