As we can see almost all people dont have real invest strategy, mostly people buy bitcoins and keep them waiting moment "to the moon".
Probably it's the most popular plan 

But surely people who trade every day ll have short term strategy as buy with lower price and sell with higher.
So seems nothing extremly extraordinary 

It's impossible to just print money. Printing too much paper drives a country into inflation. Inflation can ruin the country and destroy its economy.

Bitcoin can't be printed when more is needed.

But bitcoin has no real value, but nevertheless there is market.

There is no tangible thing that supports the value of bitcoin, that can prove there is value to it.

There's no Gold, no Silver, no other tangible item that exists in the world...just the promise that only so much bitcoin can every be mined and that the validity of transactions and balances are verified by the community that uses it.

But may be we ll have any crypto coins in future which would be proofed by something else. Probably existing of such coin would have good future!

The first thing - It depends if Bitcoin will be accepted just in one country or worldwide.

I suppose it means that we would be able to use bitcoin as secondary, official currency, for buying/selling things, many merchants would accept Bitcoin, we would have more Bitcoin ATM's, bitcoin debit cards etc.

It is good topic.
First of all it will depend on the country and the nature of the transaction.

If you are just doing private transactions there is anything to tax, but governments are getting more creative every day.  If the crypto transaction is part of a business deal I would assume that the same tax rules apply as would for a transaction with fiat money.

But for now I think some rules concerning cryto transactions are not described completely in laws.
I mean mechanism and system of laws and taxes has not been completely created.

It's interesting thought. And we should surely take care how our family or close people can get our crypto inheritance if smth would happen with us...
It is important topic and I would not be too surprised if soon we will read in news about new service or start up about how to organize such things in better way.

Why a lot of people advice to OP to make trading if question was about investment?
Probably OP does not want to trade. Some people think about trading as about speculation and/or don't want to take part because they are too nervous for this for example...
But they still can be interested in crypto world comminity and investment in development of this world.
Probably it's question about any ICO which we can expect this year or which exist now...
One of the most famous ICO now (at least as I see it) is Chronobank ICO.
There a lot of topics here in forum also about it, is it good or not.
You can find these topics here.

Here there are a lot of good replies already, but I ll add a bit.
Yes, it's true nothing would happen if you would send bitcoin to dogecoin wallet. It's different currencies and have their own databases for everything.
But there are a lot of exchange services where you can make exchange of one cryptocurrency to another.
You can use also special rating services for exchangers. You can find better rate of exchange and comments and proofs about how this service works and avoid scam. For example www.bestchange.com or smth else.

Investing in ICO is rather risky investment but it can be profitable. It's really worth to try than to try other risky investment out there.
We should look at what will be the final phase of the project. There are factors we can check to minimize our worries.
Also people who creates ICO. If they are known in crypto world, it can give some proof that it ll not be a scam.
But the main thing is final step of project and the main idea. And if it is possible to get back money and leave ICO or if you can do smth with tokens of it (if it's in tokens). It gives some proof and trust to people.

For now bitcoins are still treated by most people as speculative and investment tool. Some still believe that bitcoin price will reach 'the moon' value oneday.
But also it can be good instrument to send funds from country to country with minimal fee.

Surely posts from more experienced members are more appreciated and also more informative especially for newbies
But to be newbie does not mean to be stupid
To ask good questions is also important. I mean newbies also can ask and make discussions and get higher rank afterwards.
I think also it depends on person. Some people prefer firstly read and then ask questions and some people are lazy to read and they come to forum and create topic expecting people ll run and explain everything... I would say it's somehow annoying
I prefer read first.
But nevertheless is also possible way to get rank and as result to have Signature and take part in Signature Campaign...

Краны - очень неблагодарная вещь. Трата времени.
Но мало ли, если у кого-то вдруг оказалось масса свободного времени и все же хотите попытаться, то будьте осторожны. Среди кранов можно попасть на скам, просидите перед монитором целый день, набивая капчу, а потом вывести сатоши не получится.
Будьте бдительны.

Вам беспокоиться не стоит.
Как уже здесь написали, то тут 2 момента.
1. Могут возникнуть вопрос от банка, если большие суммы и часто. Но скорее всего это мало кому интересно.
2. Если что-то кто-то купил потом нелегальное, то это вас не касается.

It will take a lot of time when all people of the world will start using bitcoin instead of fiat currency and then they will use wallets instead of banks accounts. For now banks and cryptocurrencies ll share functions and somehow devide market. It's what we can see and it's what hapenning right now.

It's good question what is quality of post. This question appears from time to time in different signature campaigns because they want to pay only for constructive qualitative posts.
I think here there are several approaches. First - is when person is experienced and has opinion in topic which can be interesting for others. Such person can be like an expert.
But what to do if you are not expert yet? If you are rather new person on forum. Does it mean your posts are not constructive or bad quality?
It would be somehow not honest
I suppose good quality of post is when it's written with normal english grammar (can be with mistakes because for some of us (may be even for most of us) english is not native, but nevertheless text should be "readable" and "understandable".
Often managers of signatire campaigns also include as factor of quality - length of post.
So post should not be too short. It can not be "ah, yes, cool" or "haha". Surely there are situations when somehow such phrases can bring some sense or be important, but lets be honest... here it can not really be.

About designs of signatures - there are a lot of designers who can create them. There are some topics of such guys which can create them for some crypto cions.
I ve seen some really nice signatures, sometimes they are rather creative.

Users can have some signature in their posts. Type of this signature depends on rank of user.
There are companies which develop their ICO or brands what ever.
They create signature campaigns and create for all ranks several slots.
And users can join their campaign. Usually they are paid by each post once per wekk or so.
But you need firstly to reach at least Junior rank. There are no campaigns for newbies.
Good luck!

This video blog is rather useful in my opinion

Hello!
Probably you mean that you can not make a post because you are a newbie.
Newbies have limited functional. They can post only 1 post per 360 seconds.
So may be it's what you mean. Just wait a bit and soon you ll have higher rank.
Good Luck!

You are welcome!
Forum is full of interesting topics, so you need just to read more and you ll find everything you are interested in.

There is no really available campaigns for Newbie.
Need to have higher rank. At least to be Junior.
