and what you are asking is about investing in a cloudmining website, and from what you said (giving GHS for free) it seems like you have found a scam Ponzi scheme (most cloudmining sites are scam) and your answer is no, do not invest in that. if it is free and pays you enjoy it but do not give your money to them.
I would be more cautious in future. Best investment and safest investment for bitcoin is to hold it. Thats it.
I want to like you did '' to hold bitcoin '' but I am always afraid when I saw the price on market when broke a lot
do you have any suggestions to withstand fear to sell?
1. Purchased mining tools and software. Go into mining you will need to calculate your costs like electric, cooler, e.t.c
2. Trading bitcoin with other altcoin. You need to develop your skills and knowledge on forex trading, formalized yourself with both technical and fundamental analysis.
