Bitcoin may do you rich,1 btc now cost more 6000$.I was know first about bitcoin in 2013 from pool 50btc.
Yes that's true, Bitcoin is able to make you rich at the moment, because the price of Bitcoin is increasing year by year, so if you hold a lot of Bitcoin, of course you are rich.
not even just now but so on if you want. the increase in bitcoin is difficult if from year to year and surely bitcoin will experience ups and downs without us knowing because of the pros and cons that occur. we can remember it in 2017, in fact the price was high and now it has dropped dramatically.
Right in bitcoin we will have so many pumps and so many dumps, it is very natural the price changes so if the price is down we only need to hold as you said 2017 was great year in crypto currency when the price was so high and so many people have become millionaires, so still we can have that time back in our life if we will see price more than 15k in near future.
