I believe investing in bitcoin is as safe as investing in any major hedge funds.
TBH, nothing in this world is totally safe and yes, investment in Bitcoin appears to be safe but what will make it safe is determined by the investors knowledge.
A lot of investors have made losses just by having the mentality of Bitcoin being a safe investment in terms of hedge funds while they lack the proper knowledge.
The volatility of bitcoin gives a kick and it is pretty unpredictable where it will go as this market is yet to reach its full maturity. Yes it is quite safe as, it has achieved a size too big to ignore, and we are seeing its increasing day by day.
The volatility which is the great kick in cryptocurrency investment is also the reason why it generates great benefits and not knowing when the market will reach full maturity is the reason why I think we should not consider crypto or Bitcoin investment to be totally safe.
