If you strongly believe in Ethereum you can try Ethereum 2.0. staking. And now you are not to have at least 32 ETH and you even can return your money from staking earlier than Ethereum 2.0. launches. It is available because of different new projects, now I will tell you how.
To become a validator you can:
Launch your own node by staking 32 ETH;
Via non-custodial validators (p2p.org);
Via custodial services (crypto exchanges);
decentralised pools.
 Lido creates an on-chain asset, stETH (staked ETH), which is issued in exchange for ETH sent for staking on Eth2. stETH can be bought, sold and used as collateral in DeFi protocols, increasing capital efficiency and the ability to generate increased income. So your Ethereum will not be locked.

When you invest in different, not very popular altcoins, you should always be very careful, as, in case of emergency, you might be able to save your money if you act quickly. But if you don't follow the project and its altcoin you can miss some changes and as a result lose your money. It is acceptable to hold only coins and currencies that you are sure about. It might be Bitcoin, Ethereum, BNB. They have high trading volume and they are quite popular among investors.

Ideal is when you know coding at least a little, so as to look through the smart-contract that is said to be the only source of truth. Personally I check different functions like mint, transfer, setmigrator to find out how this smart-contact works. If you can't understand anything in their code, it will be a good thing to read the response of auditors if they were audited, which is also an indicator of reliability and security.

It seems to me that you bought everything on highs, it was a terrible mistake. I don’t think that this year we will see another bull market, so welcome to the club of long-term investors. We only buy more and average on the drawdowns, hold and hope for the best. One good thing for you is that you have bought fundamental currencies that are more likely to survive in the long term, but not meme coins that will die out as soon as hype is over.

Everything depends on advertisements and marketing campaigns. I am not against meme coins for fast speculations, but when it is for a small sum of money.  They don’t carry any real utility for the market and this is an actual problem. So I don’t think that they have a future. As soon as hype ends they will die,so the most important thing is not to be very greedy and get rid of them in case of emergency.

Why should we accumulate USDT? To my mind it is a good time now to buy Bitcoin while it is at 38 000$ and maybe a bit later we will see something lower to buy more.
I find Bitcoin a really good long-term investment, so I believe that in 5-10 years it will really hit 100 000$ and I will get a big profit. But now it is obvious that we will not see an increase by 3 times, as now it is time for a bear market and it might be even a crypto “winter”.

What do you really mean by dividencs? If you are talking about profit from working with crypto for the long term, there are two things that give you income. First of all, all promising tokens with innovative ideas, that will survive long-term, will cost more than now.

Secondly, I find staking campaigns pretty attractive, as this way you get both interests and some native token of project.

Elon Musk understands that it is easy for him to manipulate dogecoin’s price to speculate on it. If he had chosen bitcoin or eth it wouldn’t be so easy for him to pump it. And he can pump this coin just thanks to his authority, so it is a really good tool for him for speculation. It is a big question now if he really is going to sell Tesla for Dogecoin or if it is really manipulation.

Personally I don’t see any reasons for him to make such a decision. Dogecoin’s price will depend only on this and will be supported only by buyers of Tesla, so how will he sell this coin for large sums?

I think that he chose exactly this coin for trading as it is easy for him to manipulate its price. If he had chosen bitcoin or eth it wouldn’t be so easy for him to pump it. And he can pump this coin just thanks to his authority, so it is a really good tool for him for speculation. 

Actually, I can’t agree with you. Some altcoins carry real value, so I  stick to the strategy of choosing some altcoins in the top-100 list on coinmarketcap, and I hodl, and buy more regularly.

Of course, there are some coins that exist only for speculation but definitely not for holding, but it is your decision that must be supported by investigation of this currency.

Yes, I also think that Ethereum developers should hurry up with the update. Competition in the market is growing every day and projects such as Polkadot have every chance to take the lead thanks to the development of their own technologies. I think Dot still has a lot of surprises.

I really like Polkadot, I think the growth potential is huge, almost like Ethereum this year. It is quite possible to grow to several hundred, or even thousands or more. Many appreciated the benefits of the coin and the project, so the forecasts for the development of DOT are very encouraging.

The creation of a contract is a one-time process, so optimizing the deployment of smart contracts is not the most important topic for Ethereum right now. At the moment, there are many interesting problems of network optimization and optimization of the same smart contracts. Scaling problems will continue until a solution is found that suits the interests of all participants.

After the crypto boom burst into our lives, many imagined that they were natural traders. Because people mistakenly decided that making money on digital currencies is very easy and simple. And when it turned out that it was rather difficult to trade on crypto-exchanges and get profit at the same time, complaints began.

If web mining were so relevant, affordable and profitable, perhaps everyone would now rush to make money in this way. I got interested in the issue of mining on Coinbase, but I could not find an answer to my questions. Therefore, it is better not to get involved in incomprehensible undertakings and continue to earn in reliable ways.

As long as there is demand, there will be a market. Even as a result of weeding out low-quality projects and scam, there will be a lot of good coins in which many want to invest. The crypto market lives at the expense of investors, as long as people can make profit and benefit the life of the crypto world will continue.

You cannot compare two strong and promising cryptocurrencies. Ethereum and Bitcoin are very different projects with different goals and different development paths. I think that you can speculate for a long time who will win, but in the end, both BTC and ETH will remain in the cryptocurrency arena. 

Ethereum, Zcash (ZEC), Monero (XMR) are very worthy projects in my opinion. But how many will manage to reach the same level with Bitcoin in the face of continuous competition in the market, the big question is. But Bitcoin regardless of anything will remain the leader of cryptocurrencies in terms of both market capitalization and popularity.
Also now there is Binance Smart Chain. You can check tokens on this network (enough perspective)

Mastercard decided on such actions due to the fact that VISA took the issue of working with cryptocurrencies very seriously. This is competition in the market. The crypto space has the hope of completely replacing fiat.
