Is bitcoin still a good investment for newbies? Is it worth to pay almost $8200 for 1 BTC today?
Nobody will be able to give a defenitive answer to this question... Some people will tell you they think BTC will reach $10k before the end of the year, others will tell you they have credible calculations to support their theory it'll fall to $5k in a couple of weeks.
Personally, i'd suggest you have a look at the speculation subforum, and read up on bitcoin. If you personally believe it will rise, you can invest a little bit of your money. But never invest more than you're confortable losing. At any rate, bitcoin is a high risk/high reward investment.
Btw: you do know you don't have to buy 1 BTC at a time, right? Bitcoin has 8 decimals, the smallest amount you can theoretically buy is 0.00000001 BTC
bitcoin have reached $9,200 now and still kicking up so maybe the first speculation coming to reality to make $10,000 before year end.
And its even right to make more reading in speculation so you will have an idea what bitcoin will be for another days or weeks
