I am not planning to spend my bitcoins actually, because I am long term holder. I believe that Bitcoin's price is going to increase highly in the coming months and years, so I keep storing my BTC into my wallet as long as I haven't urgent need to cash out. We can spend fiat money because its value is a lot lower than Bitcoin.

The most valuable altcoin which have the best potential to grow up highly in the future is surely Ethereum. This coin have many attractive features and its already growing up fastly, and its price is also increasing and it is expected to go up even more in the neare future.
There are also some other promising altcoins like Ripple, Litecoin and Phore.

I think trading BTC and altcoins is a lot more profitable than mining nowadays. Mining actually is very expensive and you have to spend a lot of money for equipments and electricity, and after this you have to wait several months or even years to start getting profit. Trading can give you fast profits if you have the basical knowledge at least.

Bitcoin can reach $50k or even more of course, but not in the near future, in my opinion. The actual price is below $10k right now and it is going up slowly. Also it took several years for Bitcoin to reach around $20k a few months ago, and then decreased again. But since the price is always volatile and the market is unstable we can predict such levels in the far horizon.

There are many people working full time with crypto currencies in many ways, like trading and selling services, and so on. But you have to keep in mind that the whole crypto market is still unstable, and also the crypto prices are known by their volatility (going always up and down). So I dont think it is good choice to depend only on crypto jobs, especially if you have a family.

I know just two automated sites helping bounty hunters: bountyhive and bountyplatform. Both are good because you dont need to making reports of your social media posts for example, the first one however isn't really transparent because it is not publishing the spreadsheets. Also the bounty section of this forum is very helpful to check the most valuable bounty campaigns.

Ripple is valuable, but Ethereum is always the first choice in my opinion. ETH have the most value and potential among altcoins and it is growing up fastly, also the demand for this coin become pretty high nowadays since it is always needed for investing in most ICO projects, which will help to increase its value and price in the future, most likely.

I encouraged one of my closest friends to invest in Bitcoin and crypto currencies, because he is already working online and having some knowledge about crypto. Most people around me in my country dont interest about working online and it is pointless to talk with them about such topics, because they have already pre judgments and refuse to take any action towards investing online.

I think it will disappear but not in our nearest future, it will be used for several coming years or even decades for sure. Crypto currencies still not really popular yet worldwide, and still need long time to replace the paper money, especially most governments and banks still supporting only fiat currencies and paper money and fighting BTC.

Yes indeed Bitcoin is a new hope for humanity, because its resolving so many financial problems for a lot of people around the world.
Also since its price keep increasing highly with time many new comers get motivated even more to invest in BTC and keep holding it for long periods.

Bitcoin is very valuable just like gold but there is many differences between both of them. Mainly Bitcoin is a crypto currency even if it is currently considered as an asset. While gold is considered among goods and a physical asset too. Also Bitcoin's price is more volatile, and growing up faster than gold which have more stability of its price.

Yes I am trading at multiple exchanges, because I am trading many coins and tokens, and there is no unique exchange supporting all the crypto currencies right now. Sometimes you are forced to rgister in some exchange because the coin you re trading is only supported by that exchange, you havent many choices in this case.

Bitcoin is going to keep its first position in this crypto world for several coming years , most likely. It is the most used and traded crypto currency and also it have the biggest community. But I believe also in Ethereum, since it is really growing up fastly and having many attractive features, especially its smart contract which make the ETH platform the most preferred for ICO devs and investors.

Bitcoin is considered by most people as an asset nowadays, but in fact it is mainly a currency, and it was created to be a digital currency in the first position. But since its price is volatile, and keep going up highly with time, so many investors decided to treat BTC as an asset by holding and trading.
Also the usability of BTC as a currency still really limited either online or offline.

Yes, Bitcoin potentially can hit a lot more than $20k in the few coming years. Its price is volatile since its creation almost, but generally it is going up year after year, it go down for some time then increase again and so on, all the time. Thats still good time to buy more BTC , because the actual price still low.

Why selling if you can hold for long term and making bigger profits after few months or years ? I think holding is the best solution, especially if you dont need cash money for urgenet causes. You can selling other coins having less value than BTC or ETH if you really need fast money.
Selling ETH with low rates is not a good deal, because you re losing the chance to make higher profit.

I prefer Bitcoin, but Ethereum is my preferred altcoin currency too, so I am trading and holding both of them, and I believe that BTC and ETH have the most promising potential among crypto currencies right now.
Also many experts declared their positive predictions about this coins, and that their prices will increase highly soon.

It is always good time to buy Bitcoin if you look for long term profit, buy and forget about your BTC for few years and come back you will see that its value and price multiplied many times. If you want making short term profit by Bitcoin trading, it is also possible, but you have to study carefully the market and the BTC chart firstly.

BTC price started to go up slowly since few days, but I think it is still good time to buy Bitcoin actually, because if the market keep going up as expected the price will be much higher in the few coming weeks and months. So buying now with this low rate would be the best profitable decision.

If you are active in this forum and you have some needed skills you will get many opportunity to doing jobs for BTC or altcoins. Keep browsing the marketplaces sections daily and you will find many threads asking to complete some tasks and get paid with BTC mostly. Or you can create your own thread selling your services for crypto payment.
