I would suggest you not to sell all your Bitcoin. Keep some for the future.
Bitcoin is facing many problems today due to high transaction fees but once the lightning network is complete, fees will be lower and the transactions much faster. And of course, prices will be higher.
If I were you I would invest in my favorite alt using fiat (if I had the money).
If you are looking for quick profit as you say go ahead.

Bitcoin is not a bubble.
It's an innovation in the financial world. It evolved from the gold and silver coins to paper money and the credit cards.
Crypto-currency was the next step and it is to stay. It makes no difference if the price is going to rise or it will collapse.
It represents our fight against the monetary system and against the banksters. That's why it was made for.
The money belongs to the banks or to us. You decide.

I don't think he is taking money for promotion. He can just buy some thousands of it and make the announcement.
The price will rise and he can sell them taking profit. It's the 1 million dollar question. Which coin is going to make money today. 
I don't believe that he has a team either, he is just picking one coin. Immagine there are bots made for trading and waiting for the announcement on McAfee's twitter.

I can translate into greek pm me for information.

I don't own Ripple, in this forum the opinions are divided, but you can search in the official website of the coin.
Usually, the developers propose a wallet for each platform Windows Linux and Android. I think the coin has a dedicated forum so you can ask there and you'll find a wallet for sure.
It is an excellent strategy moving the cryptos to our personal wallets we all know what happened to MtGox some years ago.

It's my favorite investment strategy too. I didn't know this term before reading your thread.
I buy my cryptos on Monday morning and I don't care much about the price. So far it seems that this method is working.
For long-term holding, it's just perfect. In this forum, someone gave me another good advice too, If you want to be a holder do not check the prices of your coins more than once a week. He had also right, sometimes you want to cash out.

A member of our forum started an interesting experiment about two weeks ago.
He invested $1000 to the top 100 coins in the market cap ($10 each) and is going to keep them in a hardware wallet for 5 years.
Sofar (10 days later) his initial investment is already doubled.
You could do something similar for your kids, you don't have to invest in so many coins. Don't  invest more than you can afford to lose.

Sorry, I can't find the link.

I don't think banks control bitcoin. The fact that they want to ban it shows the opposite. They are interested in blockchain technology and they could issue their own crypto (mining in and taking all the profit) giving it fancy names and supporting it with gold tokens etc.
If we bite the bait we are done. Bitcoin was made to give us a bank in our pocket uncontrolled of institutions and authorities.
It is not made as an asset and when the price will be more stable, people will start using it.

Have you ever heard of Mt.Gox? It was a bitcoin exchange, it was hacked and 70% of the coins were lost.
It is dangerous to keep money in exchanges unless you are a day trader.
If you are a holder a paper waller is perfect.
Another option could be the use of an old PC (or a Raspberry Pi if you have any) in order to run a cold wallet. In my opinion, the wallets mentioned by the developers of the coins is the best software you can use. Hardware wallets have a good reputation but I've never used them.

I know McAfee and his antivirus program but not his as personality.
I can imagine him buying some thousand of altcoins and then announcing them as Crypto-currency of the week/month.
Trading is just business and he is a businessman. He is making quick money taking advantage of his popularity.
I don't say Verge is a bad investment.
A good question would be, what is going to happen after a month or two when new altcoins have been announced.

In my opinion, centralized coins are those that are non-mineable.
I've searched the net and I found that among them the following are : NuBits BanxShares Fuelcoin Stellar Counterparty NXT Bitshares.
I am not sure if all of them still exist today. Ripple is one of them and probably the new one announced in Venezuela the Pedro.
If you can't mine them, that means that the profit goes to the initial owners.
In example, Ripple was made by Ripple Labs Inc.

For the time being, I am a holder, so I don't have to send money at all. The wallets I'm using is just to check my addresses and transactions. For tokens (ERC-20 compatible) I use MyEtherWallet too. It' an excellent web page, you can use it offline, if you wish.
There are many other wallets too. Some are suggested by the developers of the tokens.
Make sure you are downloading the genuine one and not a dangerous hacked copy.

Don't lose time, invest now. If you can spend a small amount of money on a monthly basis, do it.
Choose 3-4 coins, buy them and watch their price grow.
Make your research first and don't follow opinions of unknown people, promising quick gain. You can lose your money.
The market is reckless and doesn't forgive. Remember, don't spend more money than you can't afford to lose. It is a new market, no one knows if the cryptocurrencies continue to exist the following years. 

It seems your computer has been compromised. If you're using pirated copies of programmes or you download them from unknown resources, you have probably a trojan or keylogger in your system.
If you make many transactions it's better to buy a ledger/nano.
The other option would be using a dedicated PC for sending coins, Myetherwallet is a great program it worths using it,. but not in a compromised computer.
Unfortunately, many of us have made the same mistake...

Litecoin is one of my favorite coins. It has a good price and very low fees.
It's not growing fast as some people expect and it's not volatile. The last days we saw a price correction after the pump during holidays.
When I've read that lightning tests include Litecoin too, I was sure it will go up in the future too.
I don't like either that Charlie Lee left it but it was time to stand on its own value.

It seems that you are very new to this forum and you have the impression, that prices are always moving upwards.
This is hardly happening. If you are going to be a holder in the future, you will notice, that there are alts moving fast and disappearing in some months and others with most stable prices.
Volatility is something common in the crypto world and must not make you nervous. Just be sure that it worths owning the alts you buy.

You don't have to worry even if a war happens. During the 1st and 2nd world war the battles were located in specific areas of the world.
In the rest countries, life continued normally. The communications were working even in the conquered by the Germans areas.
The internet is a web and will always work.
The miners will exist to mine in the free of battles areas and the people will keep the personal keys in papers CDs and USB sticks till the end of the war.
N.Korea is not a thread.

When I've started buying in the crypto world I knew just one coin, BTC.
Later after reading a lot and watching hours on youtube, I found out that there is potential in other "alt" coins too.
I am a holder and not a day trader. I avoid following others opinion and I am not attracted by names or promises of quick money.
I am lucky because I don't have a lot to invest, I am struggling to make my living, but I have hope and nothing to lose..

There is no one knowing what is going to happen in the future.
I am quite sure that more than 50% of the coins you see now in the market are going to disappear till 2021. Many new ones will come, some of them better than the current ones.
My opinion is that you can invest even today. You don't have to give a fortune. $30 at the time or less is enough.
Read the forum, you'll find a lot of information, make your research before you buy.

Ripple is made from a company named Ripple Labs. They own all of it.
It was not made as a cryptocurrency but as a medium to exchange money between banks.
The company has pumped it and now they are cashing out. Be very careful with it. It is not sure it will continue to grow if you buy a lot and the price falls you may get trapped.
There are many other real cryptos that are decentralized. Make some research before you buy.
