Bitcoin is going to zero if you like it or not.
For the moment I am looking for a buy opportunity as everyone is scared and want to cash out.

The biggest question that you should ask yourself is why bitcoin is going up and why is going down ?
One thing only which is squeeze.

Long and short squeeze.
Back in 2017 the only reason bitcoin was going up is because of short squeezing if that is a term.
Amateur Traders kept shorting looking for the top " with the help of the crypto delusional of course thinking that bitcoin is their lotto ticket" they are forced to close their position "AKA long bitcoin or buy Bitcoin" which leads to increase in price.

The opposite happened few months ago:
Plenty of traders were shorting the 6k area, gets a pump to 7k they are forced to close "Buy bitcoin"

The most likely scenario that is going to happen now is to spread fear and uncertainty so everyone goes short.
That is your moment to buy to ride with another short squeeze.

Buy on every dips, hodl it for the time it rises. Such falls are normal today it falls and tomorrow it rise eg few days ago it fell $9200 and then suddenly it shoots up to $10200 in a matter of days.

There are always a few red flags for scams:
- no real/verified profiles for team members
- no or bad references on other websites
- poor social media activity
- poor Whitepaper

If you want to invest an important amount of money, you should better opt vor Bitcoin, not Litecoin.
Bitcoin has adoption and development going for it. Bitcoin owns crypto hashrate, security, basically impossible for reorgs/double spends.

Altcoins (like Litecoin) don't have nearly as much development and adoption. LTC is basically a code copy of BTC, with much less developers (if any? recently Charlie Lee basically said he's the only one)

While Litecoin might be good for a little gamble, Bitcoin is by far the best for long term future investment

It all depends on what alts you hold. You cannot compare ETH, LTC with all the sh*t coins that appear on market like mushrooms after rain.

Currently is not a good time to buy. The market is bit unstable for new investors. It's better to buy either bitcoin or litecoin/Eth when the market is stable.

First, never invest in crypto more than you can afford to lose and second, stay away from privacy coins. You see already privacy coins being kicked out of exchanges making them going slowly down to natural death.

Crypto is a big marketing gag of big bankers to implement full digital currency into the new monetary system.
Next step are regulated stable coins,governmental stable coins and security tokens.

The rest will die.Bitcoin will have its peak arround end of 2020 and after that it will slowly die.

The problem is that between the 3 Bitcoin is the only one that does not have a concrete value. If nobody will want Bitcoin tomorrow the price will go to zero.

Or it is not the case for gold  or stocks. By having gold you  an built your own jewelry and sell them, owning stocks you own basically a small part of a company. What do you own by holding Btc if demand will decrease drastically one day?

Why would anyone need a new wallet if there are already a lot of good wallets on market?

If you have important amounts of money invested into crypto, just buy a hardware wallet (Ledger nano s,  Trezor  etc) and your funds will be safe.

This is normal to happen in 2019. Every serious project will choose an IEO eventually, not an ICO, except if they have things to hide or if they just want to vanish with people's money when ICO finishes.

As an investor you have a better visibility via an IEO and you'll know from the beginning on which exchange the project will be listed on.

The main problem with Btc as an alternative payment option is that fees are still too high. On exchanges it cost you about 5$ to transfer your Btc.

Alternatively, you can buy and send an alternate currency like Bitcoin Cash with a lower transaction fee and then transfer it over to Bitcoin via an exchange once it arrives. You may lose less from transferring between currencies sometimes than you do in sending and transaction fees.

If you want to avoid being hacked you should think about using a hardware wallet (Ledger Nano, Trezor etc).

Even if your PC is infected with viruses or malware,  the private key will never leave your device. However,  always double check the destination Btc address.

This is exactly the reason why we need crypto in our lives. Governments can print money to the infinite. You'll have physically more dollars but they will worth less. This is the effect of inflation.

When Bitcoin will be adopted world wide on a larger scale, inflation problem will be fixed, as you cannot just print new Btc.

ICOs are already dead, imho. You you are a serious project and have nothing to hide, why would you choose an ICO instead of IEO?

IEO offers much more transparency and it's a more efficient way to raise money for new projects.

There are multiple ways of earning Bitcoin. The easiest and safest one is to join as many airdrops and bounty programs as you can, and when you get paid for it, just sell the coins you receive for Btc.

As it might take months or even more than one year to be paid for some bounties, you can try to trade on exchanges, too, but do a lot of research to learn trading fundamentals first and never invest more than you can afford to lose.

You should always verify the destination address of your Btc.

QR is nothing but a faster way of sending your Btc. Behind there is the same principle: the address,  that might be unfortunately hacked. So, be careful.

It all depends on market cycle: you should keep top10 alts mostly during bull markets. If market is bearish you might want to keep more Btc than alts.

It works in both cycles, in bear and bull markets. The differences are number of opportunities to enter into trade. In bull market you would find much more opportunities to enter, in bear market less.

Price always retrace no matter if price consistently pussing up or dumping, eventually it will retrace and you must break even or make profits on these retrace. But I agree that in bull market its easier to make profitable trades.

Here you can find some reasons why most of projects are not successful:

- they are not original and just copy ideas from other existing projects;
- no vision
- team's members have zero experience in crypto/marketing projects
- their products/services have no real added value for users.

Bitcoin is raising a lot of additional opportunities for freelancers. There are a lot of websites that pay you in Btc to perform different tasks.

As a freelancer, to be paid in Btc all you need is a laptop with internet access and a btc wallet. That's all. You can do money from any side of the world.

You need to understand that Bitcoin cannot be simply banned as long as Internet will exist. Your government blocks you from changing  your crypto to fiat in your country? No problem, do this when you go on holiday in other countries.

Another alternative would be to buy goods directly via Bitcoin as a lot of merchants already accept Btc as a payment option.

First, nobody knows when a quantum computer will be released and also nobody know how Bitcoin will look like when this is gonna happen.

I think it's way to early to think about this right now. If a quantum computer will go live, imagine that all the other payment systems (banks, PayPal etc) will be affected,  not only Btc.
