There are 2 types of people who want to make an investment, first who afraid to start and second is who wait for a good moment to enter.
The first one isn't an investor.
Since he's afraid to start, why call it as an investor if he don't even have the initiative?
But at first i am the first one, don't know where to start especially at past crypto is new for me, but after did it i think people include me will start to know and can decide which one is profitable.
You should do your research to know what are the profitable cryptos that you're good to start with.
You are right, at first i only know it maybe safe to made investment in Bitcoin or maybe Ethereum because that 2 big coins will increased and i only know about it and don't know about technical analysis yet. But it change because more practice we can know and decide which investment will made us profit because there are a lot of chance in altcoins if we pick right coins it will be profitable for us.
