I participated in the Credits Project (CS) and after completing the ICO it was commercial and I got the x5 amount that I had invested. It was a wonderful result from the ICO project that I participated in, so I will not forget that feeling.

My best ICO experience is EOS, i gain lot of my properties by investing in this project. Now, it is sitting at TOP 4 in coinmarketcap. I think in the future, when main net of EOS is released, this price can reach 50$. And I am holding 5k EOS right now. Waiting for the uptrend of crypto market and the future of EOS

my best ico is lympo.. and now i try to focus on hashcard.io

My best ICO experience is Ambit Mining ICO https://ambitmining.io/ as the project has already running in profit before the ICO launch so there is no doub that it will reach to boom.

NebulaAI is a project that has paid very high generosity. In addition, NBAI tokens have grown almost 2 times in a week

in on of my icos the price went 4x lower and an idea came to me, to buy more in the dip and for one night the price came into the ico price which was 4x higher but I sold at 2x 

So far, the best have been Lympo.

I invested with moderate research, as it was my 2nd ICO investment, and I've learnt from the mistakes I made in the first.
I got in pretty early, securing a 25% bonus. Since then, I only saw positive things from the team, at least one announcement per week. The idea behind the project is one of a kind, there are no, or very few competitors.
Also, the coin price is around 4x of my investments, even if it's not a big value.
I'm really happy with the team and the project. Going to hodl until at least Q4 2018, as I see steep increase in value, and when the application will be finalised, it will surely increase the price of the coin.

What is really interesting is the company wishes to do an IPO in the future. I don't know how will that affect the coin price, but I believe it will positively.

If you remember all the ICO, which were, then I will call the best ICO Ethereum, as in the end it brought its participants a huge profit. As far as I know, last year the most profitable ICO was Populous.

My best Initial coin offerings experience was the one with electroneum. Yes the launch of that coin was very hard. They hat to relaunch their wallets and it needs more then an month for that. But it was my first ico and and i made the most profit of it. When it was launched, i sold it on cryptopia and make a 15x gain. I just inested a small amount because it was the first ico and the first contact with cryptocurrencies for me.
