Lots of people especially those with little knowledge about Bitcoin and it's mode of operations, would be wondering why Bitcoin is the most talked about crypto asset to invest on currently but this image below would help enlighten them with a clue to what they need to understand.
The picture depicts exactly what other investable assets can do and how bitcoin distinguishes itself from them. From onset, anything that is scarce, rare and a very reliable and useable commodity, it will have great advantage over others that can easily be accessible, re-modified, recycled or even recreated. Bitcoin has become an asset that has grown in a very small time to overcome other investable assets that have been existing for many years. And with its consensus in which it operates on; the concept of decentralization, it will go far and be the most sort out asset for investment as the price continues to grow and exceeds the expectations of many investors in the market.
As you can see, unlike other Assets, Bitcoin is a decentralised asset and can't be created more, but increases in value when it's price is halved. But note that Bitcoin as an asset is very volatile in nature, therefore you shouldn't invest all your savings but a spare money you could lose without getting very emotional. However everyone needs to take advantage of this years halving and take profits to prepare for the next very early.
I would rather say that investment in bitcoin is not based on what you can afford to lose, because no one that has invested in bitcoin and waited for a long time that didnt reap their profits in it. When youre talking about invest what you can afford to lose, it should be related to altcoins and not bitcoins. 1BTC will always be 1BTC until you spend some part of it that its value reduces. So investment in bitcoin should be what you are able to spare for the long term and not to use until your profit target is reached. Talking about emotional and losing funds, it should be on altcoins and not bitcoin.
