Yes agree with you that dollar is the strongest currency but it has some reasons like dollar being the most used currency in international trade and to settle claims around the world.Moreover most of the countries maintain reserves with them in respect to dollar and oil barrels are sold in market with dollar prices.So it remains at top in all currencies.

If the person is really interested in knowing the working of crypto coins then surely he will get its working and technology behind it but some people have negative viewpoint about it due to rumours about its volatility and scams like btc being bubble.Others just want to get rich by btc without knowing that it is coin used for payments not mode of getting rich.You can invest in it and wait for long term and get returns in future.But slowly people will start getting its importance and adopt it.

Hackers can't reach offline wallets so they are safe but your freind might have been attacked when he was onliine on messenger and they stole the access to private keys at that time.So never store them in online way.

It was quite a good time when LTC hit $140 in the previous years but now its down due to dump situation in the market but yes its good time to buy litecoin as its cheap now and when btc will surge its also going to hit $140 or even higher again so i am going to hodl it until that time to gain much higher profits.

Its not the case only with ETH but almost every coin is witnessing bloodbath from last 2 years but now there are some positive signs in the form of price growth so you don't feel disappointed in this phase because ETH will soon cross $300 mark as it trading roughly between $220 at this time.You need to be patient if you want returns.

Although the market is volatile and price can go down but it seems difficult to me that it will go down once again to low level of $5000 as it has managed to reach $8000 and now we will see bull run soon hitting the market.The investmemts are increasing pumping the prices and increasing the demand so be patient until that time.

In my opinion there are certain limitations which need to be covered in crypto world like
1-Proper knowledge of working behind these coins or technical knowledge and level of skills
2-Higher transaction fees and limit on certain amounts
3-No support from people and governmemts
4-Greed among people which leads to scams.
But all these can be covered if we give our full support to the system and blockchain technology which will provide us a better world.

My larger part contribute towards bitcoin which is 55% of my total investment and another 25% is settled in ETH and rest in other altcoins.I am long term hodler so i choose them.

You must have joined here a long time ago because at this time the market is not good or say it is disturbed as prices are fluctuating highly but still it is said its never late in this market. So you are welcomed. But your knowledge is not accurate as to you said altcoins = Fiat which is not true as they are volatile but fiat has stable value and can be exchanged for any item.Moreover there is competition among altcoin not between btc as it is king of cryptos and dominates the market.It has potential to rise above lower levels as it is trading at $8500 starting from $3-$4k last year and help boost the price of other coins.

I don't think so that people are loosing interest in bitcoin or other coins but on the contrary basis i would say that due to social media and news publicity of these coins have increased and more wants to know what actually these digital coins are and how they work.But if you are talking about young investors leaving market due to price dumps then they don't really know it's power and potential to rise in future. The market volume is still high and will keep on growing with more persons joining market.

The governments around the world are recognizing the importance of crypto or say more of the blockchain technology so as to boost the economy of the country.Same is the case with Ukraine as they have submitted the bill to legalize it but still they are way to make it happen but they have exempted earlier to crypto holders to pay taxes and other exemptions.The nations who have a positive attitude towards crypto market knows it importance and its usage so they are going to give give profits to the market in form of price rise.

Casemiro and Busquets have shown over years how important is defensive midfielder role. Both in creating chances as well as defending, these two outshined last decade. Hands down, Casemiro has been best madrid player alongside Benzema this season.
Jovic made shit move coming to Real that soon. Currently Benzema is first striker of the team, also there are lots of big wingers and forwards in team, Jovic won't get enough minutes to settle in Madrid. He has almost thrown his career in vain.

See its the case with many bounty campaigns that they make changes at the time of payment but we cant say anything about it as they have already mentioned that that have rights to make changes in the agreement.Its upto you that you want to participate or not.They make changes to avoid problems like dump situation or any other issue.Make your own decision before joining.

If you are looking to invest in bitcoin then i would suggest that anytime is best when you choose to invest your funds in bitcoin because if you are long term holder then prices will rise in future and you will get profits.See if the prices rise even to $20000 by 2020 then you can buy even at this prices also.But don't be too late to be part of the race. 

If you have proper knowledge and skill to implement in this highly volatile market then you can generate profits in any case even in up or downstream.Traders get oppurtunity when prices fluctuates to move their investment and benefited from it.Manipulations are always in every stream and whales manipulate prices in crypto market.So its just your decision that which time suits you.

Financial crisis have been always a problem for developing nations due to incorrect monetary policies of the government and yes it can be solved with the help of gold reserves or btc as we have seen Venezuela arising out of crisis with crypto involvement.So it might be helpful for world economies but fiat will always have fixed value and cannot loose its value in case of inflationary measures also.But we don't need to think of another economic crisis due to trade wars as they have been part of political system of countries.

Its really good to see NGO's adopting digital currencies like bitcoin and contribute to the innovation of blockchain technology.We are aware of the fact that now most of the institutions like UN is also accepting btc as deposits feom the investors and others are also on the way.They might not have reserves for such currencies and exchange them in fiat immediately or later but its good they are helping others in any form of money they get.We can't argue on this topic.

See this is the main problem with most of us that if see prices tends not to rise we simply imagine that crypto market will be ending soon and such things but this is not true in actual sense.Although you have traded from this year prices are down from 2017 last qaurter.But with increased adoption and investment btc will again gain dominance and prices will rise so stick to your investment and hodl it until price rise.And if you are interested in altcoins invest in only those who have developmental plans or objective in long run which can give you profits otherwise don't invest in others.

The governments might legalize bitcoin and it can be used as legal tender or legal currency but it cannot be replaced by local currency of the country as fiat is physical store of value which can be exchanged for anything without the use of any internet transaction.There will be many people who would adopt btc but still people will prefer to hold fiat with them as its easy to use and without any complications.And there can be negative and positive effect like boosting of depressed economies or increasing illicit use of funds.Anything can happen who knows.

Actually the crypto market or btc is a decentralized coin which cannnot be controlled by anoyone but the prices can be easily manipulated by the whales to gain profits by creating pump and dump situation as there is no regulated body to act upon.It is coin held by many investors and prices will rise with increased demand and supply becoming low.So we can say it is free market and nobody owns it.
