Indeed, which is why many people (including me) look for the most ethical investments, avoid buying products from companies known to exploit their workers or pollute the environment etc. My very presence on this planet will inevitably impact it and my fellow citizens but there are still choices I can make which affect whether that impact is for good or ill, or at least minimise the ill.
I asked where the money I might make from buying and selling Bitcoin would come from because I genuinely don't know, the whole cryptocurrency thing is a complete mystery to me. I recently chose to invest £5000 in a community solar farm project, maybe I should indeed have used it to make millions out of Bitcoin and donated them to charity instead. So I would appreciate an answer, if you have one.
There are several strategies one can use. All it takes to get started is to open an account at a reputable cryptocurrency company. You can quite literally control your investment vehicle from the comfort of your home. Buy in, sell, get out or repeat. If you buy and sell from your account you can deposit or withdraw directly to your bank.
Some buy in, hold their crypto and simply wait for an increase in price. Others buy in and day trade when the market has some decent volatility. (So far in the past 48 hours BTC has had a $1600/coin price difference between the daily high and low. A decent trader would have likely realized $1000 per Bitcoin average profit over this past 2 day period) I've said it before and I'll say it again, it's relatively easy to make $1000 a day trading cryptocurrency. Do that 1000 times and you've made your first crypto million. Or make $2000, 500 times or $10,000 , 100 times.
Bitcoin should be considered as a commodity for trade IMO. Speculation is where the money is, again IMO.
Anyone can become a trader. Simply start small to practice buying and selling, learn how the fees work and at what price point you can sell to be in profit. Your calculator becomes your best friend. Or some choose to buy and hold. Holding is a sound strategy but may take longer to realize profits. Set yourself a magic number and if or when it arrives sell half or all of your bag. (half means you still have coin in case you missed the top)
If it sounds interesting go for it. If it's not for you at least now you know.
BTW, the community solar is usually a scam. If it's sponsored by your power company you end up paying about 3 to 4 times what the solar panels actually cost and they usually cut you off the program after 20 years, even though most panels still produce 80% of wattage as they did when new. At least that's the scam they run here in the States.
