Are the crypto groups that on telegram reliable?
Please care to mention some groups that you follow and have a good success rate.

Bitcoin price was around 1000$ exactly a year ago. Not many people knew about it and hence not many people invested in it. During this 1 year, a lot of people have come to know about its potential and also considering it not as a mere currency but also an investment. Bitcoin hitting $3k mark may seem as a shock to a lot of people but it paves the way for those who missed it during its rise(last year). Try to take this in a positive sense. Bitcoin, Ether dipping is an opportunity for all those who 'missed the train'.

You'll know the answer to your question within a month. Binance is one of the largest exchange and its coin has a lot of potential. Its market cap is less.
The best thing about this coin is that the coins are burned and supply is reduced with the hope of increasing its value. The previous two burns resulted in the coin going 100x the first time and around 40x the second. Nobody knows when the third burn will take place but since it is on the low side, its a good time to invest in it. Maybe for 1-2 months is good.

Don't really understand your post.

Encryption of any kind never hurt anyone. It is just done to keep the information secured. It has been used since world war 2. Even today if you haven't noted, I'll tell you that whatsapp and telegram also use end to end encryption while sending data to other users.

Yes monero is a good investment. With growing popularity of this coin in the dark web, it surely gives a good competetion to bitcoin.
It's surely a good investment for long time.

We've seen currencies going haywire in the past. Bitcoin diamond (BCD) always pops up whenever there is a drastic change in the value of the currency. $19 one day and almost reaching $100 the next day.
Is it safe to invest in it now?
Or should i wait for it to drop more?

This is my list(with reasons):-

Vechain - Bringing the supply chain management on the blockchain. Supply Chain Management is something that'll not end as long as the companies in the world offer goods and services to the customers. Expect this coin to grow in the future.

Monero - This coin overcame some of the limitations or rather enhances the privacy and scalability that most altcoins and even bitcoin does not offer. There's the reason darkweb is craving for this coin.

Neo/ethereum - Both are same in a lot of ways. Neo, also known as ethereum of China, is a project that offers Smart contracts, decentralized apps(DAPPS).

Litecoin - Less hash block generation time(2.5 minutes) so faster transactions. Fees is nominal. Less  supply, so has the ability to shoot up in the future.

I'm amazed at the level of newbiedity in this post.
Could you tell me who are the people you're referring to?
And bitcoin has just stabilized. Expect an increase in the price soon.

If people still haven't noticed, Binance coin is on the verge of shooting up. It's time to get rich everyone. Do buy BNB now.

Don't put all your eggs in one basket. Invest in other currencies as well.
In my opinion, you should buy those coins that have less volume. You don't need to get too technical and study the whole whitepaper. Study their price chart and the special features of that coin.

The fact you're posting this tells me that you're a materialistic person. To have value, it's not necessary that it should be sold in the market or have a physical appearance. It should just fulfil the needs of the people.
Love, the most important thing in the world, does not exists as a material. You can't buy, sell, throw, play or as a matter of fact, take it inside you. It still exists. Doesn't it?

Over the years we've seen how bitcoin has become the pioneer, god of cryptocurrency. This community is the result that bitcoin is working fine and after 9 years it has still maintained it's integrity and we as a community will not let it die.
I want to know has Bitcoin ever been hacked? Has it ever had any issues with security? And no i'm not talking about the exchanges being hacked. I'm talking about the blockchain network it offers.

No surety is there in crypto markets. But we can predict the future by looking at the past. It worked the last 2 times. It is very likely that a currency value will increase after burning. Read this. BNB being less in volume and still burning has a high possibility of increasing after burning.

To all the people who are still mourning/whining the crash of the market(even though it has stabilized and it's increasing now) and are looking to get back in the game, here's a good news for you all. Binance coin(BNB) is all set for the third burn and you should start stacking up your BNBs.
Here's the article - https://www.cryptorecorder.com/2018/02/18/the-upcoming-march-burn-will-push-binance-coin-bnb-to-50/

The market looks stable now. There won't be a huge dip anymore(like it happened in december). Though with people investing more and more in bitcoin will result in a significant increase in it. So you can definitely invest in bitcoin right now.
Altcoins may increase if the respective organizations tie up with other organizations so it's market is not the least predictable.

To know that you'll have to read a lot. Some of the coins that I personally think have a huge potential are Vechain and ethereum. They both gave me good returns in the past.
I can say with absolute surity that Vechain has a lot of potential. It is not due to the returns that it gave me but the concept is quite nice.(offering blockchain as a service). Do give a read about it.
Peace.
 

The fact that you're posting it here tells me that either you're not in their telegram group or you don't follow it. It is down for sometime. It'll be up and running in no time.

So is it recommended to buy coins which have less circulation?

Are there any coins which are deleted as the time passes so as to decrease the supply and increase its value?

Also i would like to know about coins which have less circulation supply than btc and are less in value.

It's resolved. With discount.  . Sorry for the panic post Binance.
