I believe that bitcoin would drop to around $5000 and i am planning to sell my bitcoins right now and then buy them back later when the value drops to around $5000
Suggestions are appreciated
If you're sure that bitcoin will decline to $5000 level, you can sell now and buy in there with almost 20% more bitcoin. If you have 1 BTC now, it will be 1.2 BTC if you can achieve this plan.
But there is no guarantee, if it start an up trend, you will miss the opportunity.
