Hello dear, all information you have shared have good to understand,
Let me write what I know;
Check the coinmarketcap.com and choose ones with high volume
Check the projects
Check the chart, if it is pumped, don't buy, wait
Check the chart, if it is dumping, wait for low volatility,

I think the main thing is to check the market trend and bitcoin movement because when market is in good condition you can say when the green trend and selected coin technology improve or any other good changing will happen than in responce the price will go up very positively and when the market is in down trend and any good changing happen in your target coin than it will not be effected such a good ratio that happen in another market trend, So i think the main thing is to understand the market trend for good profit and good earning choices instead of all other infromation because in up trend mostly coins are moving upword with only market position and if any development than they are moving high unexpectedly and the chances of profit are also high,

I get an education about crypto from some websites and from youtube channels and I think these channels are good to get information and training and the expectations of different expert traders relating to crypto and when I have  need to get knowledge about crypto I like to visit on them,

https://coinmarketcap.com/
https://cointelegraph.com/
are good websites to get real information,

Yes it is good to learn because everyone has no good understanding and all knowledge and this is the platform which you have good things to learn that makes you able to take some action regarding the trading and understanding the trading,

My strategy is buying coins and sell it at a high price when the price is down to buy it and hold it and if the market goes more in down than buy it again and if it will go more down than buy it again in 3 lowest and after buying hold it and wait until the market go up, when the price will go up than sell it and earn more profit,

It is very simple to start trading you have minimum 100$ and with learning about training you can get from YouTube channels that are a good thing and after that, you have different exchanges and coins which you can select and buy at low price and then sell it at the high price,

I think there are lot of trading tricks you have to learn from the market but I mention one very easy and single suggestion for trading that is according to the market position and after taking decision for example currently the red zone is showing and after some time it will go to green and by understanding this thing if bitcoin will not move unpredictably than you have the best option to buy coins at this rate and sell it at high rate when market will stable,

I think these all options are good but the main thing is how to do if you do this with proper understanding and good knowledge and with good training then you have a good skill of trading and you are a good market understanding trader and have the skill to choose the best option in according to the market position because the market situation is the main thing to understand other things comes next.

Market is very simple to understand because currently every coin in red zone and it is very right time to buy, I think you have a great option right now select the good coins and invest on it to earn good profit and this is most good time to buy and sell in after the stable position of the market or when market shows you greenery then you can sell it at high price and get a good profit,

Bitcoin is the most valuable digital currency in this word and it is having great demand because of latest blockchain technology and limited quantity and the price, I think bitcoin is the best option for long-term holding and it makes you able to get more profit in future because its price will increase and long-term holders can earn great profit from it,

Its good to start trading and if you do this very correctly and with good understanding then you can get good profit from the crypto market, In the crypto market, you can earn great amount and it will good to you for more profitable,

Yes it is same as which you have observed, Bitcoin is a king and all other coins are working according to them If the unexpected movement will occur in the price of bitcoin than all other coins will be affected very badly and the price is going to the dark red zone in some time because bitcoin directly effect on it,

If you want to trade you must have at least $100 and then you  can do any trade by using exchange which you want because if you have less than $100 you cant trade because it is a minimum balance which you required,

I think it's about two stages, If this same thing happens with me, If the market down very darkly but the coins still in my exchange than I hold for a very long term because the market will take too much time to recover the prices and the next thing is I need to control my emotion and fixed a plan that waits until price comes back and I think its best to do because it is good option instead of selling in loss,

I think you can choose some good coins which are available at the lowest price and the very best option to get good coins that are almost all are in down price currently, ADA Coin, TRX and Stratis are best to buy and some other good coins are also available at lowest price choose any good coin and earn a good return,

Yes Currently Bitcoin price and Eth price is too down and it is the best time to enter the market with these  coins and choose any good coins instead of these to buy for long-term holding or short-term trading both options are good because currently all coins are available at low price and when the market gets stable your investment come into profit and if market goes up you can earn good money,

I am trying to buying altcoins at cheapest rates when market goes down I try to pick good coins to buy at cheapest rates that are plan and after some time when all market will go to high prices than I can sell it that is my goal and in this way I will get success to earn more money,

These are the market trends some time all market go to the down and in this condition, few time green and most of the time red zone is displaying but it is not permanent when the market will make stable than all coin again to greenery,

Bitcoin is blockchain based decentralized cryptocurrency this is used in all around the world some countries ban but most of the developed countries are working on this technology bitcoin is limited in quality and because of its new technology world is hungry to get it because a lot of big brands are accepting big business mans are holding and that is why their value is increasing day by day,

Hello dear, there are a lot of wallet of bitcoin available to hold bitcoin but I think you must use good bitcoin wallet and I think there are two wallets are the best wallet to hold bitcoin,
1, Blockchain Wallet
2, Coinbase
I think these wallets are the best wallet to save bitcoin,

I think you have a very better option to invest in ICOs, You have a great opportunity to choose any good ICO and buy their tokens with 30% Bonus and after buying when the token comes in the market you can sell it with profit and the bonus profit also in this way you can get maximum profit from ICOs,
