They buy it and keep it for years, for a lot of growth.
If you can spend a lot of money and wait so much, then it will be a good investment.
If not, either forget about it, or try to trade on cheap coins.
And for this you need to be able to read graphics.
Not much only $500 I can invest now and I can hold it for 2/3 years. If I don't have much money then I will not invest in Bitcoin? I'm not clear.
Invest as much as you have and hold, price is going back up and soon we will start to make new ATH prices. You need to be with clear mind, there is a lot of fud around but bitcoin can cost 100000 dollars in couple years, do you personally believe in that? If you believe then buying under 50000 dollars is great chance for anyone to double the money, and if you invest 500 dollars today in two years you can have 5000 from that.
Like others said buy now, and buy when ever you have some spare money and wait. Crypto is different from forex, cryptos are the future and when you think about possible prices in the future now its great time to invest while prices are low, how much will rise nobody knows but trust in one thing bitcoin surprised us many times with very high rise, that can happen again, not just one more time.
Thanks for your nice advice. I'm going to invest $500. It's my first invest. Of course, I'm investing my free money.
