BTC is expensive in the eyes of some beginners, but successful people are usually people who are able and ready with all the risks seen now it is expensive for BTC, but if you are strong and hold it until time, I think 2 units of mobile phones even more you will get back with a better brand.
My friend, the post-halving moment will provide something big later even though there is a slight difference later because this moment is eagerly awaited by many people including you and all who believe in bitcoin. Yes. You've made a bold initial decision of course
Purchasing bitcoin is not expensive because you can start holding a bitcoin as low as your pocket can. That is just the point, so if you really want to start investing, you can buy based on the money that you know you can afford to lose, which is based on the risk in bitcoin. Normally, anything that you want to do in this life requires a good insight into the associated risk as long as you are dealing with investment. So, selling his phone won't be a great risk for him since, from his context, he has more than one, but the main factor to consider is: can he be patient enough to hold it for a long period of time? Because he is diving in with a small amount of capital as an investment, it will take time before you can get a profit, so a lot is involved.
