When you are going to invest in real estate, it means that you have to pay a LOT of money. When you deal with altcoins, the starting investment can be even $20 or less. Naturally, the bigger sum you use, the larger will be the profit.

You will go nowhere with just $20 though. Though its better to just invest few but with $20 you will have to wait for more than years before you can have a good amount. If you can spot the better project which can yield good returns for you, spend money to invest to it. If you see EIDOO is a good investment, buy more tokens. Or at least at every dip so you won't spend a lot to a token you want to invest with.

Think that it is a good investment due to the fact that it is raising fast. I mean the market of altcoin. As for me, bitcoin is better for you to choose. I will consider investing in bitcoin after considering all pros and cons. This is a new way to earn a living and I like all innovative solutions

The only reason is the opportunity to earn big money in a short time, for example, some altcoins may go up by 60-90% in a few days 

I think that altcoins are really good choose because they are more perspective. So choose NEO and IOTA.

because by investing Altcoin we can control and manage the level of capital to profit directly and at any time without having to wait for the company to act and take a lot of time in every process for a decision we want.

Investments allow people with ideas to implement them, not all of them are useful or necessary, but believe me, it is worth it. Change is always good no matter good or bad.

The meaning of altcoin i guess is investing online money into real money. The why we invest? Because people need more insuficient income and need extra money.

I think if you want to invest in altcoins it is a good choice. But you need to choose proper, and be ready to lose your money because crypto is quite risky.

It's like investing in bitcoin. Investing in altcoin can be an alternative to bitcoin. Altcoin prices are much more affordable and can get more coins.
Based on the data in the market, many altcoins have greater increase than bitcoin. So investing in altcoin is also very profitable, but it needs a lot of experience and knowledge.
Investing in real estate or stocks is also profitable, but it takes a long time and smaller profit.
