Hardware wallet or password encrypted file with your seed or private key. And when we think about clients, then Bitcoin full node is the safest one. For Ethereum you don´t need to download full blockchain history, just use Metamask or Myetherwallet.

Wash trading and reporting fake volume is a criminal offense? I didn´t know it, but how the other exchanges do that that they still operate even everyone knows that they do it? List of exchanges with fake volume: P2PB2B, Latoken and Bithumb.

Of course that bounties are profitable, probably you don´t know it but you answered your question already.  As you can see a lot of us wearing signature and participate in the signature campaign. Did you see someone to do something for free? Not that often, right? Still, it is possible to earn a nice sum of cryptocurrencies, I don't intentionally say money. 

ICOs that were managed in late 2019 and 2020 provide similar excuses, due to COVID-19, they can´t follow the roadmap and everything will be postponed. We know how it will end up. After a few months team will be completely silent. 

She also said that they understand that XRP shouldn´t be volatile before banks start use it. But what does it mean? And how they achieve it? If they manipulate the price to make it stable, then all XRP investors wouldn´t be pleased.  

Yes, they survived the longest and worst bear market in history! Now I believe that altcoins will have only good times, investors will come back to the market and see that altcoins survived and that they are stronger than anytime before. A lot of coins upgrading to the new chain: ETH 2.0, NEO 3.0, Tron 4.0, IOTA 2.0. 

On Coinmarketcap the coin is still not ranked because probably Coinmarketcap didn´t know the current supply. Secondly, they swapped the old DOT coins to a new one with a 1:100 ratio. Last time when I wanted to buy Polkadot, it costs 3 times less, probably we will see another bull rally on PolkaDOT coin, they are at the beginning.

We thought that a cryptocurrency based on a joke with the Meme logo can´t survive. But, it was proven that we were wrong. Around the Dogecoin was a great community created, it has itself marketing, look at all Dogecoin memes and even in 2020 still, Dogecoin is so popular. A few weeks ago there was a TikTok challenge to buy Dogecoin, again created as fun. But you see, it works!

Look in my signature, Oikos provides decentralized finances on Tron network. By lending OKS tokens you get syntheticUSD and with sUSD you can buy also sETH or sBTC and hold them into your personal Tron wallet. Or you can use Justin Sun´s Tron DeFi project - JUST.

There are two different ideas about how cryptocurrencies look in a few years.
The first group of Bitcoin maximalists says that there will be the only Bitcoin and anything else is useless, worthless.
The second group says that technology is every day more and more advanced and old blockchains will be replaced by a new one.

This is what we call dangerous of centralized projects, especially when it is managed by one person. McAfee showed again that he is a schizophrenic person and we cannot trust his words or deeds.

While everyone is looking for DeFi projects that are now hot and overbought. Why not do things differently, try to look at coins that has real-life use cases. For example supply chain coins like VeChain, TeFood. When this hype around DeFi ends, people will again look for alternatives. 

Hello, I wanted to buy Netflix and Spotify, but on the shoppy website I can´t find it, so you probably don´t have them right now, right? Please tell me when you expect the delivery of these products and approximate prices?

Because people do not behave rationally, but emotionally. You can learn about this interesting fact in this book: Thinking, Fast and Slow by Daniel Kahneman and you will know about the market´s behavior, you will learn how to advertise your product and much more . This fact could be applied in various ways, also we see that the crypto market is a good example  .

The opposite! Thanks to airdrops and bounty campaigns people get informed about the project. It is true that people earn free tokens and they rather sell them than hold because they do not know what they really get, but on the other hand, it could mean cheap tokens for investors if the token is really valuable. So no, bounty campaigns do not kill a project, the team´s inactivity kills it.

The most difficult question is what is the optimal yearly interest rate. When you give a high-interest rate, you attract investors on a big profit, but sooner or later it will cause a big inflation.  Someone researched this field? What is the optimal interest ratio? 

There are several good tips on how to become a bounty hunter, I just would like to recommend some good bounty campaigns where you avoid wasting time and your diligence. Oikos is currently the hottest bounty campaign due to its working DeFi solution. Try to find a campaign that still accepts new participants .

I thought few months later that crisis will come and every financial asset will fall down, also cryptocurrencies. But this didn´t happen and Bitcoin is at the year´s ATH price. The conclusion is that do not try to predict the market, do the dollar-cost-average strategy .

But something should be behind this token because I do not believe that only hype can make this coin the 50th biggest cryptocurrency. Someone on twitter said that YFI token gives you an opportunity to claim dividends from the fees that the platform collects.

As far as I know, it is still not available for every country, I am still on the list. The only way how can I get the profit is by referring to new people. For every new referral, you got 5 bucks in BAT token.
