If you own the bitcoin, there is no need to worry about growing your bitcoin as its price will rise in the future.
but like i say before in other thread, holding is not a best idea for growing our money, for me trading is best option, we can use small percent to take profit maybe 5% permonth then in 1years we can growing our bitcoin with interest 60%
Mate You need to review or smart to do, that's mean "Chance" so invest be smart, For ponzi scheme it's just bullshit, only snipe there.
agree with you, ponzi is not recomended place to invest our money, the system is very bad. better we build bitcoin mining rig.
