Congrats!
Your Blog has the most fitting design, I would go for a bright orange as opposed to the current yellow.
The Blog also covers various topics which would be very Search Engine friendly which is bolstered by using the Blogger Platform.

One advice though would be to have a more memorable and/or brandable name that is not => http://cryptocurrency-investments.blogspot.com

something as:
cryptoinvestments.xyz
CoinVestments.xyz
CoinVestments.blogspot.com
CoinVestment.xyz
CoinVestment.blogspot.com
bitvestment.xyz
CryptoVest.blogspot.com
bitvestment.xyz
bitinvestor.xyz

could be more memorable or/and brandable, It is all up to you.

To finalize my review, very informative content which I hope to keep an eye on.
If you need any help, Feel free to contact me.
Wish you the best on your blogging journey!
