Investing can be a double-edged sword in the sense that it is both subject to risks and yield. But if you study carefully the risks associated with an investment, you would know how much risk you can take and how much money you are willing to invest. For me, I only invest my money in things that I am really familiar with. Like in stocks, I only choose companies that have a long history of stability and profit-making.
A successful investor is not always perfect, there are some successful people come from failed investment experience and at least get their money back with no profit. some investment will never happen without failure, this is an anti-mainstream procedure. If you kind of people who play safe, you will only feel successful in one way, nothing more.
Agreed, in the cryptocurrency world you cannot be succesfull all the time, it is going to be there sometimes when you lose, but losing is part of learning and developing an experience so one day you won’t fall into the same mistakes again, and you have to take the risk otherwise you won’t earn anything with bitcoin.
losing is not important, but how you handle that loss is important.
lets say you have bought Dash yesterday at 0.04
BTC price and wanted to make profit but price started going down and finally reached 0.03
BTC as of today. if you just blindly wait and hope for profit you have already lost in trading and better stop doing it.
but if you start acting more logically and sell at 0.039 for instance to prevent more losses and buy back at the bottom if you still think it can rise
Doing it the way you describe is in fact not particularly different from what you preach against. How come? Because it is basically the same gambling as just waiting out the bad times. And if a coin has a genuine potential, it may be better to actually wait out without hastily closing your position (this what Warren Buffet is famous for, i.e. sticking to his guns). Even if you are strictly into day-trading and don't care for fundamentals, it still wouldn't work unless you count in a lot of other factors. For example, it doesn't make sense to buy when the price is going down (otherwise you may end up catching falling knives), and that's still more true with regard to altcoins which may and often do turn completely useless and worthless in the end. It makes more sense to buy when the rising trend has already established and not close your positions until it is clear that the trend has reversed
In other words, thoughtlessly putting stop-losses can be as detrimental as not putting them at all
I think you can earn in few services or just like signature campaign you can earn few bitcoins and you can use them and scale up them to make more money but it is depends what plan and methods you are doing the risk still there if you are using your money instead of using for your skills..
