Patience, Trust and Intelligence. These three are the rules of HODLing. Do not dump you coins when you think value is good enough, wait for the coin to blow up. That's the patience necessary. How do you know the coin's gonna blow up? Believe in it. Have trust in the coin and do not let go easily. Which coin to trust? Search for the coin, understand everything. It's up to you, be intelligent. That's it. Always have these three feelings for a coin.

Fiat currency is go-to currency everwhere in the world. It is used EVERYWHERE. The world ran on Fiat currency for so long. But sometimes, it can lead to problems. Fiat currency can be stolen and be destroyed. Crypto currencies cannot be easily stolen. Someone can hack and take all your coins, but there are people who try their best to prevent this too. I would prefer a world that runs on Crypto rather than Fiat currencies, just because it is easier to use and is, in a way, a safer way of exchange. But, this cannot happen right now, because not everyone has access to crypto currency, Internet and Technology required for crypto altogether.

There are SO many altcoins. The top coins have a lot of stuff going on and are doing really well. Altcoins, Bitcoin altogether, wouldn't go down so easily. There are millions of people whose lives are based on Bitcoin. They'll keep the community alive and well. New coins with  brilliant new features keep coming out. 5 years is enough time for new, better coins to take over the current ones, that is if the top coins like Ethereum go down (which won't probably happen in a short span of 5 years). Therefore, no, altcoins and bitcoin will be alive for more than 5 years from now.

Crypto currency is an AMAZING opportunity to earn money. If you have the brains for it, you can try and earn 1000$ a day by doing a lot of work at start, and then just letting the market do it's job. But, it's not for everyone. There can be a lot of scams and you can end up bankrupt too. There is a lot of risk involved. If you're smart enough, you can live off of crypto and lead a pretty good life, but crypto is unstable and can be disastrous at times. Having a safe job with job security is always beneficial. Crypto as a side job while working at, let's say a cooperate office, is probably the most stable, middle clase life you can lead.

Okay so the thing with KYC is that it can greatly reduce scammers and that can be awesome. Still, KYC is something that is used for Intitial Coin Offerings (ICOs) and it is personal information that can be used for scams and therefore it is VERY dangerous to submit it to unknown people. I, personally, am sort of reluctant to submit KYC. Although, it wouldn't be that big a problem to submit it, I'm afraid of letting people know my personal information.
