Simple ICO smart contract.
This smart contract allows you to conduct a fundraising event for the initial coin offer (ICO) for various projects. Implemented such features as softcup, refund, bounty, etc. More detail information in pdf files: https://github.com/plexar88/ico/blob/master/ICO%20smart%20contract%20for%20TON%20network_EN.pdf
and russian version:

> If you call send_raw_message(dest, 128) and then call send_raw_message(src, 64)

I like your way of thinking. And there is also raw_reserve

We found some critical issues in your contract.
- `collected_funds` is wrongly calculated if an investor buys tokens multiple times. In the latter case `total_spend_grams` is increased by `inv~load_grams();`, so previously added funds will be added again to `collected_funds`.
- The contract ignores existence of processing and storage fees, so during refund the contract can run out of funds.
- If (now() == date_end), then ICO can succeed without reaching softcup.
