You can avoid your fear in trading by investing very small amount or the amount which is completely affordable for you to lose,then just do trading just like the gambling if you don't have any knowledge but you will learn from your mistakes once you started but long term trading is good to start initially for the beginners.

Most of the reputed exchanges have used friendly interface so you can learn that in minutes after you entered into the site but you should select the exchange based on the coins and its daily volume,you need to choose the exchange with much volume for easier trading or you need to wait long for that to happen.

I really don't know what is the meaning of RTP because I never tried playing in the bustabit,but maybe you can ask these question in their ANN thread to get the answer if there is a legal way to do.But if you mean by how to increase your winning percentage then there is no answer for your question you should rely on your luck for this to happen.

I don't remember my very first bet because I used to gamble in very early ages in unofficial casinos but it will be very small money because I can able to use only my pocket money for any purposes.But I remember my first bet on the online gambling site which is about $100 in the sport betting but unfortunately I lost there.

I think we no need to worry even if the bitcoin miners uses lot of energy because we have lot of methods to produce the electricity even for few more centuries just like the hydro power,solar,wind power and mainly the nuclear power plants but most of countries excepting the nuclear power plants because it doesn't harm to the environment but in future if there is scarcity for electricity we can use them at great extent.

Sadly lot of people forgets that the inflation rate so they are just losing their money day by day in a small rate,if someone want returns then they should go for an investments there are lot of investments are available other than the crypto currencies so they can invest on those but they also need to understand the risk of investment before doing that.

Easy task = less rewards and signature campaign= good rewards,so you have to select which one you want on your requirement but if someone looking for more rewards then they should go with signaute campaign and more over the campaigns like youtube campaign,blog,article like that since many people won't concentrate on those campaigns.

If you want high rewards then you need to concentrate o the signature campaigns and Youtube campaign because the number of participants in these campaigns will be low so you will have more rewards based on the stakes calculation.

You should invest on ICOs:
1.If you know about how to find out the legit and scam projects.
2.If you are looking for profits in short term.
3.If they have good promotional strategy.

Yes that is true,the long term trading or the holding is most beneficial and effortless and it also easy when compared to the day trading we can invest on the best crypto currencies and need to wait for the profits but the one important thing is that patience since the market is always swingy so you may tempted to ee your coins when you see the low prices so learn to be patient then you will made more.

It looks like the OP created this thread just to increase his post count and activity because he is active after this thread created but never made a reply here and just posting some one liner replies in the random topic and one comment made me laugh that by OP is 

Using large amount of electricity is not a problem but how they are making that electricity matters,if they are using electricity from renewable sources like solar,wind and hydro power plants then they can talk about the environment issues but electricity is the reason for transferring from physical money system into cashless system?

First of all if the bitcoin price goes up there is no need to be that altcoins needs to go up as well and also there is no best coin to invest,if you found one then you will be a millionaire.So try to do your own research understand the risk involved and invest on the coins which is best in your opinion.

It is not going to reach that much value because we only have few months left so th prices will not reach $20000 even if the bull run starts now.But why people are still thinking about $20K? just forget about it and buy it at the current price since it is very much cheaper.

Why he replied to DMs or PMs if he is legit then he need to post that on the bounty thread but instead of that he just locked that bounty thread and vanished again,pure scammer's thing.

Set the target and sell your coins if you are a investor and don't want to make money in short term.

If you are a trader you need to consider about these news too,if there is negative news about crypto you should sell at the point when the prices started to dump.

It is possible if the crypto trading stops and bitcoin payments accepted world wide but for now it looks too early many people don't acknowledge the existence of crypto currency and the people who knows it using for making money with its volatility so too early to say that we are independent of fiat money but the time will come and we will use our money with full freedom.

The security of the funds is very much important in the gambling sites because there are some big whale payers only deposit their money if they can have them safe and withdraw at any time without any restriction,but OP now needs to concentrate on specific reputed games other than including all the games which make the cost more wider,it will be better if he can stick with one game and make it better in all terms which can provide the profits once the players started to play.

Sadly most of the crypto investors and traders failed to follow this rule while they are entering into the crypto field.But later they are worried about their mistake,so remeber that prevention is better than cure and don't be too greedy are the two things which can save ourself from serious problems which also suit for any thing in our life other than crypto investments.

Answer unknown for everyone,so please don't ask silly questions again.The price of bitcoin is swinging between the range of $6000 - $6500 for last few weeks so don't consider it as a fall if still it is swinging in the range.
