As for now btc is constant on 8 to 10k $ and it will take too much time now to reach its peak of above 20k $ per bitcoin and the fact is no one can guess when it will grow that much in upcoming time may be next year or after 5 year but all believe it will cross 20k $
but did u guess last time right and sold all ur btc at 20 k $ cause me sold it that time and buyed after 1 month on 12k $ peak luckly me guess it right
Cool if you sold at 20k it is best as you would have made some decent money during those times and should have bought more when market fell till 6 -7 k as you would again had made money as already it is at 9 and will move now to above 10k and you will need to wait till 12k for break even.
That was a very good decision. Now, the guy has enough money to invest it in the currencies that will gain very soon. He can deal not only with Bitcoins but with the cheaper alts like NEM, IOTA, and TRON.
