...If bitcoin investment is as easy as you think, i believe everybody would have invested in it.so holding bitcoin for a longer term is not as easy as you think, bitcoin investment require patience and high risk tolerance .
...Investing is not difficult but maintaining their portfolio after investing is difficult. Because there are many people who have less patience and they withdraw it after seeing some profit after investing. A person has to be patient until the end of his investment period. You can invest with a small amount of money in the first place.
Well, it's quite difficult for some newbies cause they come into it with the wrong impression and get disappointed when it doesn't go their way, which is making quick profits but then Bitcoin investment is easy for one who knows and understands it better, it has a process and when you follow the due process of investing in it then it won't be difficult, yeah there would definitely be challenges which makes it not totally risk free, challenges like maintaining your portfolio, being patient, securing your portfolio but those challenges should be a minor one for someone who understands it better, maintain discipline and remain patient through the process. Also, not everyone invests in Bitcoin cause not everyone understands it so that's the difference but someone who understands it won't find it very difficult.
