Looks like this is your own fault.
1. You are still new but have dared to invest that eventually lead to losses.
2. If you install a blockchain wallet you should store the key in several alternatives.
Many people have regretted their mistakes but repeated them. I hope you can learn from this mistake. Never trust any investment if the manager is not you. Keep your wallet keys properly, make 1-3 storage alternatives. Currently there is no need to regret it, you can still try to find it (BTC) to set aside a small portion of your salary, because I believe BTC is the future of digital money that will be accepted by many countries of the world.
That's right, be a manager for your own business. Do not overly trust any investment party, especially those whose origins are not clear, and offer you large profits. Start with yourself, intend and believe in your heart that you can carry out your own investment. Indeed, at this stage of learning it is difficult, even many of the beginners choose not to continue because they imagine the losses they have experienced. Do not regret what has happened, what happened let it happen, you have to focus on your goals, if you really mean it will definitely get a good solution. Don't be afraid to fail again, I'm not telling you to fail again, but if you experience another failure, learn from that failure, don't fall for the second time on the same mistake. Start with the basics first. Everything is versatile in this internet age, you can learn it via google.
If you have an experienced friend it is much better to be a mentor and teach you how to trade properly. Usually, the mistake is to invest too much of the funds you have, start with small funds first. If you already understand how to get a profit, then you can use a fairly large amount of funds to generate more profit. However, do not use all your funds to invest, reserve it to anticipate if something happens that is not supposed to be desired. Because, loss can come at any time without us expecting it, even though we have done it right. Make yourself comfortable in investing, because it is your own money, so you must be able to manage it yourself. Trusting the broker is okay, but there needs to be a really convincing consideration of this.
