Usually they recommend you to diversify your investment, so you avoid losses.
But as a real approach, having $1.5k, would you invest in how many cryptocurrencies ?
What if I invest little by little, only in Bitcoin, would that work as well ?
Bitcoin surged to a new high of $X today, up over Y percent from Z months ago. If you had invested $A just B years ago you would have made $C and youd be filthy rich.
Currently, this is the only way most people talk about bitcoin. Its viewed as a buy and hold vehicle for fast capital appreciation. But the savvy investors and smart money around the world is far more focused on how to actually use bitcoin than just getting their hands on it and holding.
